How it's used

This term is considered vulgar and blunt, functioning similarly to the English word poop or take a dump. It is strictly avoided in polite or formal social settings where more euphemistic expressions like 去廁所 or 方便 are preferred. Using it in front of strangers or in professional environments will likely be perceived as rude or uncouth.

Examples

He went into the toilet to poop and hasn't come out for a long time.
Do you have a stomach ache? Why do you keep going to poop?

Common mistake

Learners often mistakenly use this term in polite conversation because they learn it as the direct translation for to defecate. Always opt for the neutral 去廁所 when speaking to people you do not know well.
