Thai Slang You Will Actually Hear (ngong, sâep, bpang)
What you will be able to do
Follow the informal Thai in a group chat, an office lunch and a bar, know which words are warm, which are only for friends and which you should recognise and never say, and stop guessing at the handful of phrases every foreigner in Thailand gets asked about.
Textbook Thai is the Thai you use with officials, and it will carry you through a visa run, a hospital and a lease. It will not get you through a lunch break. The Thai people actually speak to each other is faster, shorter and full of words no course teaches, and the gap is wide, because Thai marks the relationship between two speakers where English leaves it unsaid because Thai marks the relationship between two speakers in almost every sentence. Slang is not decoration on top of that system; it is one of the places the system is doing its work. Using a friend's word with a stranger is not a small stylistic slip, it is a claim about closeness that the other person has to react to. That is why the useful question about any slang word is not what it means but where it came from, because the source tells you most of what you need to know about the audience. Four sources between them cover most of what you will hear. English loans reshaped by Thai phonology are the safest: they carry no regional marking and no rudeness in them. What they do carry is age: they are young, urban, school-English words. Isaan words that went national are warm and informal, fine with friends and colleagues, occasionally a little cheeky depending on what you are describing. Wordplay on ordinary Thai — a taro root for a nosy person, a bird for being turned down — is where most of the fun lives, and most of it is safe — though wordplay is also where a good deal of the sexual slang sits. And then there is the rough vocabulary, which is genuinely rough, and which foreigners get wrong more often than any other kind because they hear it constantly and conclude it is casual. It is not casual. It is intimate, which is a different thing. Start with the single most useful word on this page: งง (ngong), confused, my brain has stopped. It is not rude, it has no register problem at all, you can say it to your landlord or to your boss, and it describes the state a learner is in several times a day. งงมาก (ngong mâak) is completely lost. Thais use it about themselves constantly, so saying it about your own Thai lands as honest rather than as an apology, and it almost always gets you the sentence again more slowly. The English loans are the group to reach for first. ชิลๆ (chin chin) is chill, and it works as an answer to what are you doing, as a description of a bar, and as a way of telling someone to calm down; it is also written ชิว and said chiw, and you will hear both. ฟิน (fin) is the blissed-out feeling of the first mouthful or the aircon after the street; it is usually explained as a clipping of ฟินาเล่, finale, though that is an account rather than a proof. อิน (in) is being deeply into something, a song, a series, a cause, and อินมาก (in mâak) is really feeling it. เว่อร์ (wôe), from over, is over the top, said of a story, an outfit or a person. ดราม่า (draa-mâa) is a public row, usually online. Notice what happens to the sounds: Thai has no final l, so chill becomes chin, and the loan is reshaped rather than borrowed intact. Say it the English way and you will usually still be understood, but you have said an English word rather than the Thai one. แซ่บ (sâep) is the best example of the second group. It is the Isaan word for the sharp, spicy-sour kind of delicious, it came to Bangkok with Isaan migration, Isaan food and Isaan music, and it is now national. About food it is safe with anybody. About a person it means hot, and that is a friends-only use. เด้อ (dôe) is a common Isaan sentence-final particle, warm and countryside-friendly, and using it in the north-east usually gets you a delighted reaction; using it in a Bangkok office is a joke rather than ordinary speech, which may be exactly what you want. The wordplay group is where most of the fun lives. เผือก (phèuak) is taro, and it means nosy — it stands in for เสือก (sèuak), the coarse word for butting into other people's business, the same dodge as เชี่ย for เหี้ย: เผือกมาก (phèuak mâak), so nosy, is teasing rather than an insult. เนียน (nian) is smooth of texture, and it describes someone slipping something past you — quietly jumping a queue, quietly leaving early. นก (nók) is bird, and to นก is to be turned down after asking someone out. โดนเท (doon thee) is literally to be poured away, and it means stood up or ditched. ติ่ง (dtìng) is a superfan; said of yourself it is fond and self-deprecating, said of someone else it has a light sneer in it. ปัง (bpang) is the sound of a bang and means stunning, said of an outfit or a performance. ตัวแม่ (dtua-mâe) is the queen, the one who sets the standard. เก๋ (gěe) is chic — older slang that never went away, used of a bag, a café or a haircut. Two reactions are worth having ready because you will need them within a week. จริงดิ (jing dì) is seriously?, and its gentler cousin is จริงเหรอ (jing rǒe). ว่าไง (wâa ngai), literally say what, is what's up, and it goes sideways or downwards, between friends or from someone senior to someone junior — never up, and bare at a stranger, a vendor or anyone older it is close to rude. เฮ้ย (hóei) is oi or whoa, a shout of surprise or a way of grabbing a friend's attention; the same word aimed at a stranger is a provocation. Now the rough vocabulary, honestly. เหี้ย (hîa) is a water monitor lizard and one of the strongest swear words in Thai, and you will hear it every day: in traffic, on building sites, between friends who mean it affectionately. That last use is what misleads foreigners. ควย (khuay) is anatomical and just as strong. แม่ง (mâeng) is a rough intensifier, roughly bloody, milder than the other two but out of place at work. Thais soften these in writing and in speech, and เชี่ย (chîa) is the commonest dodge for the first of them, still rough but less so. The rule that actually protects you is not about the words. It is that a foreigner swearing in Thai is heard completely differently from a Thai doing it — as aggression or as a performance, rarely as fluency — and the cost of getting it wrong is much higher than anything you gain. Learn them so you know what has just been said about the traffic. Leave them there. One structural point that saves you from a whole class of mistake. Thai slang rarely works by taking a polite word and making it ruder. It works on the machinery around the words: ครับ and ค่ะ get dropped or softened to คับ and ฮะ, and ผม and คุณ give way to กู and มึง. Between friends the particles ครับ (khráp) and ค่ะ (khâ) disappear, the pronouns disappear, and what is left is short. That absence is information. If you keep the particles and add slang vocabulary you will sound odd rather than rude, which is a good place for a learner to be. Nothing in the rough group is rescued by a ครับ on the end. If you drop the particles with someone you do not know well, the vocabulary will not save you. Add slang words first and drop politeness last, in that order, and let the other person go first. Finally, proverbs. They are not slang and belong to a different, older register, but Thais quote them the way English speakers quote proverbs — in the middle of ordinary conversation, usually the first half only, expecting you to know the rest. They are worth recognising for the same reason as the swearing: not so you can produce them, but so a sentence about a buffalo listening to a fiddle does not stop you dead. There is a short list at the end.
Everyday reactions
| Thai | Sound | What it means, and who says it |
|---|---|---|
| งง | ngong | Confused; my brain has stopped. The most useful word here, and completely neutral. งงมาก is totally lost. Safe with your boss, your landlord and the immigration officer. |
| จริงดิ | jing dì | Seriously? Really? Between friends. จริงเหรอ (jing rǒe) is the version you can use with anyone. |
| ว่าไง | wâa ngai | What's up? Literally say what. What's up. It goes sideways or downwards — between friends, or from someone senior to someone junior. Bare and aimed upwards, at a stranger, a vendor or anyone older, it is close to rude; with a particle, ว่าไงครับ or ว่าไงคะ, it is ordinary and you will hear it from shop staff. |
| เฮ้ย | hóei | Oi; whoa. Surprise, or grabbing a friend's attention. The same shout at a stranger is a provocation. |
| ไม่ไหว | mâi wǎi | I can't take it; I've had it. Of the heat, the workload, a joke that has gone too far. Not strictly slang, but used like it. |
| เว่อร์ | wôe | Over the top. From English over. Of a story, an outfit, a reaction. |
Saying something is good
| Thai | Sound | What it means, and who says it |
|---|---|---|
| ปัง | bpang | Stunning; killing it. From the sound of a bang. An outfit, a performance, a photo. |
| แซ่บ | sâep | Spicy-delicious — and of a person, hot, in a frankly leering way. Isaan, now national. Safe about food with anybody. About a person, friends only, and not about anyone within earshot. |
| ฟิน | fin | Blissed out. The first mouthful, the aircon after the street, the last episode. |
| อิน | in | Deeply into it. อินมาก is really feeling it. Of a song, a series, a cause. |
| ตัวแม่ | dtua-mâe | The queen; the one who sets the standard. Admiring and a little camp. Very common online. |
| เก๋ | gěe | Chic; stylish. Not really slang at all — an ordinary colloquial word that has stayed fashionable for decades. A bag, a café, a haircut. |
| ชิลๆ | chin chin | Relaxed; taking it easy. From chill; Thai has no final l, so ชิล comes out chin. It is also written ชิว and said chiw, and both are current. Both an answer to what are you doing and a description of a bar. |
People and social life
| Thai | Sound | What it means, and who says it |
|---|---|---|
| เผือก | phèuak | Nosy; sticking your nose in. Literally taro. เผือกมาก is so nosy, and it teases rather than insults. |
| เนียน | nian | Smooth — in the sense of slipping something past you. Literally smooth of texture. The person who quietly jumps the queue is เนียน. |
| ติ่ง | dtìng | A superfan. Of a band, an actor, a series. Said of yourself it is fond and self-deprecating; said of someone else it has a light sneer in it. |
| ดราม่า | draa-mâa | A public row. มีดราม่า (mii draa-mâa), there's been a row. Usually online, though it has long since moved into speech. |
| โดนเท | doon thee | Stood up; ditched. เท is to pour away, โดน marks it as done to you. Of a date or a friend who did not show. |
| นก | nók | Turned down; missed out. Literally bird. Mostly of asking someone out and being refused, but also of tickets you did not get or a job that went to someone else. |
| เด้อ | dôe | A warm Isaan sentence ending. In the north-east it will delight people. In a Bangkok office it reads as a joke — sometimes exactly the one you want. |
Hear it, do not say it
| Thai | Sound | What it means, and who says it |
|---|---|---|
| แม่ง | mâeng | Bloody; damn. A rough intensifier, milder than the two below. Normal between friends, out of place at work, and jarring from a foreigner. |
| เหี้ย | hîa | A very strong swear. A water monitor lizard. You will hear it daily, including affectionately between friends, and that is exactly what misleads learners. Recognise it; do not say it. |
| ควย | khuay | An obscenity. Anatomical, and as strong as the above. Same rule. |
| เชี่ย | chîa | A softened form of เหี้ย, two rows up. The common dodge in speech and in writing. Still rough, just less so. |
The phrases every foreigner gets asked about
| Thai | Sound | What it means, and who says it |
|---|---|---|
| สวยมากๆ | sǔay mâak mâak | Very beautiful. The phrase foreigners meet as "suay mak mak". Not slang at all: สวย beautiful, มาก very, and ๆ repeats the word before it. The repeat mark is explained on Read a real LINE chat. |
| จุ๊บๆ | júp júp | Kisses. The sound a kiss makes, used like xx at the end of a message, and written by English speakers as "chup chup" or "jub jub" because จ is voiceless and unaspirated, which puts it between an English j and an English ch. Love and affection in Thai has the rest. |
| 555 | hâa hâa hâa | Hahaha. 5 is ห้า, so a row of fives reads as laughter; more fives, bigger laugh. Written chat has a whole system of its own, covered on Read a real LINE chat. |
| กู / มึง | guu / meung | The intimate I and you. Warmth between old friends, a provocation to anyone else. Thai pronouns covers when it is which. |
| ฝรั่ง | fà-ràng | A Westerner — and a guava. Not an insult on its own, whatever you have read. The compound ฝรั่งขี้นก is one, so listen for what gets attached to it. It is simply the word, and it is the same word as the fruit. |
Proverbs, which are not slang
| Thai | Sound | What it says, and what it means |
|---|---|---|
| น้ำขึ้นให้รีบตัก | náam khêun hâi rîip dtàk | When the water rises, hurry and scoop it. Strike while the iron is hot. Probably the one you will hear most. |
| ช้าๆ ได้พร้าเล่มงาม | cháa cháa dâi phráa lêm ngaam | Go slowly and you get a fine blade. Slow and steady. Often said to someone rushing their work — or their Thai. |
| สีซอให้ควายฟัง | sǐi saw hâi khwaai fang | Playing the fiddle for the buffalo to listen to. Wasting your breath on someone who cannot appreciate it. |
| จับปลาสองมือ | jàp bplaa sǎwng meu | Catching fish with both hands. Chase two things and you lose both. Said about jobs and about people. |
| ไก่เห็นตีนงู งูเห็นนมไก่ | gài hěn dtiin nguu, nguu hěn nom gài | The chicken sees the snake's feet, the snake sees the chicken's breasts — neither of which exists. Each of them knows the other's secret. Said of two people who cannot expose each other. |
| รักวัวให้ผูก รักลูกให้ตี | rák wua hâi phùuk, rák lûuk hâi dtii | Love your cow and tie it up; love your child and beat it. Still widely quoted, and a window on an older idea of what care looks like rather than current advice on raising children. |
Common mistake
The trap is not any single word, it is where you learnt it. Slang picked up from a Thai partner is the slang of one household, slang from a series is written to sound young, and slang from a bar is the register of a bar. All three follow you into the office. Two specific mistakes are worth naming. Do not use แซ่บ (sâep) with a person as the subject, however clearly you meant it about the food in front of you. Aimed at someone you have just met it is heard as you're hot, not your cooking is good. And do not conclude from hearing เหี้ย (hîa) every day for a year that it has softened; it has not, and a foreigner using it is heard as picking a fight rather than as fitting in. One more, gentler: ฝรั่ง (fà-ràng) is not an insult. It is the ordinary word for a Westerner, and also the word for a guava, and there is no slight in it unless someone works hard to put one there.
