stupid like pig
Meaning & Usage
"dumb as a pig / pig-stupid"
The pig variant of the animal-stupidity simile. Ironically, pigs are actually intelligent animals, but in Vietnamese folk culture, they represent laziness, filth, and witless gluttony. Being 'stupid like a pig' implies not just low intelligence but that your stupidity comes from laziness and overconsumption.
Examples in the Wild
A mother scolding a son who failed his exam: 'Suốt ngày chơi game, ngu như lợn!' (Playing games all day, stupid as a pig!)
When to Use It
Context
- Casual conversations with friends
- Informal settings where profanity is accepted
- Direct confrontation (use with caution)
Avoid
- Professional or formal settings
- Job interviews, meetings, or customer-facing situations
Cultural Context
Slightly different flavor than 'ngu như bò.' The cow version emphasizes slowness; the pig version emphasizes the moral dimension of stupidity — you're dumb because you're lazy and self-indulgent. This is the version more likely to be aimed at someone who failed because they didn't try, rather than someone who tried and failed. In the Vietnamese zodiac, the Pig year is actually auspicious, creating an odd cultural dissonance.

“fag / queer”
Derived from the French word 'pédéraste'. It is the most ubiquitous term for a gay man or an effeminate male in Vietnam.
đm
“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.
xạo lồn
“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.
mẹ mày
“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.
địt mẹ
“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.
địt mẹ mày
“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.
vl
“holy shit / very / wow”
Texting abbreviation for 'vãi lồn.' Expresses surprise or intensity.
bố láo
“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.
