Vietnamese swear words

“fag / queer”

Derived from the French word 'pédéraste'. It is the most ubiquitous term for a gay man or an effeminate male in Vietnam.

“fuck / wtf”

The texting abbreviation of 'đụ má.' Two letters that every Vietnamese person under 40 can decode instantly. It's become so ubiquitous in online spaces that it functions less as profanity and more as punctuation — surprise, frustration, emphasis, even approval.

“bullshitting / talking out of your ass”

Lying, boasting, or fabricating stories to look impressive. 'Xạo' means lying/fake; 'lồn' is added purely as an aggressive metric of magnitude.

“your mother / fuck you”

Just two words — 'your mother' — but in Vietnamese, this is a complete insult. You don't need to specify what about their mother. The implication hangs in the air, and everyone fills in the worst possible meaning. It's the loaded gun of Vietnamese profanity: the trigger is pulled by context.

“fuck your mother / motherfucker”

The full Northern form with the target pronoun attached. If 'địt mẹ' is a grenade, adding 'mày' is pulling the pin and throwing it directly at someone's face. This isn't venting frustration — this is declaring war.

“motherfucker / fuck your mother”

Northern Vietnamese equivalent of 'đụ má.' Uses formal 'mẹ' instead of casual 'má,' making it more severe. The gravest insult in Vietnamese culture.

“insolent / cocky piece of shit”

Someone who acts arrogantly above their station. It literally combines 'father' (bố) with 'insolent/fake' (láo), implying someone is illegitimately claiming the authority of a father figure.

“stupid bastard / dumbass”

'Thằng' is the male classifier that already carries contempt — it's what you use for boys, servants, or men you don't respect. Pair it with 'ngu' (stupid) and you've got a complete dismissal of someone's intelligence and social standing in two syllables.

“holy shit / very / wow”

Texting abbreviation for 'vãi lồn.' Expresses surprise or intensity.

“cunt-face / fuckface”

Your face looks like female genitalia. It's as crude and direct as it sounds — a pure shock-value insult that combines the face (your public identity) with the most taboo body part. There's no subtlety here, just maximum offense per syllable.

“you maniac / you psycho”

Calls someone a crazy thing — not a crazy person, a crazy thing. The 'đồ' classifier does its usual work of stripping humanity. 'Điên' alone means crazy; prefixing it with 'đồ' makes it a label, a permanent diagnosis rather than a passing observation.

“whore / thot”

Northern Vietnamese slang for a sex worker. While 'đĩ' and 'điếm' are traditional dictionary words, 'phò' is pure street vernacular.

“fuck off / get lost / scram”

Dismissive command to leave. Stronger than 'đi' (go).

“damn it / dead dog / son of a bitch”

Originally 'dead dog,' used as expletive like 'damn it.' Can also describe a hated person.

“vibe killer/obnoxious bitch”

Describes a person or situation that completely ruins the mood, stops progress, or brings extremely bad luck. 'Hãm' means to brake or stagnate; combined with 'lồn' (cunt), it refers to someone whose very presence is an irritating obstacle.

“talking out of your ass / capping”

The Northern, non-vulgar equivalent of 'xạo lồn'. To tell tall tales, lie to impress, or exaggerate significantly.

“shameless person / thick-skinned bastard”

Your face is so thick that nothing — no embarrassment, no social pressure, no shame — can penetrate it. In a culture where 'mặt' (face) is everything, having a thick one means you've abandoned all social contracts.

“damn your father's grave / goddamn you”

An exclamation of extreme frustration that invokes the grave of the listener's father. Not an attack on the father, but swearing 'by the tomb'.
