Meaning
Literally 'rotten face'; looking unhappy or annoyed.
Cultural Background
In Laos, maintaining a 'sweet face' (nā vān) is a social duty. Being 'nā bū' is seen as a failure to contribute to the collective happiness of the group. Parents often use 'nā bū' to tease children out of a bad mood. By labeling the face, they make the child self-conscious of the expression, often leading to a smile. Lao language uses many food-related metaphors for emotions. 'Bū' (rotten rice) and 'Som' (sour) are frequently used for negative moods. On TikTok and Facebook, Lao youth use 'nā bū' in captions for selfies where they are pretending to be annoyed or 'salty' for comedic effect.
Use it with 'Het'
Adding 'het' (to do/make) before 'nā bū' makes it an active verb: 'to pout'.
Watch the Tone
If you say 'Bū' with a rising tone, it means 'crab' in some dialects. Keep it low!

The 'Nā Bū' Defense
If someone calls you 'nā bū', just smile and say 'Bǭ dāi bū!' (I'm not grumpy!) to instantly break the tension.
Smile Culture
Laos is the 'Land of a Million Elephants' but also a land of smiles. 'Nā bū' is the antithesis of the Lao social ideal.
