How it's used

This phrase is a vulgar way to describe someone acting irrationally, stupidly, or out of character. It functions as a strong insult or a rhetorical question to challenge someone's sanity. Because it references bodily waste, it carries a harsh, aggressive tone that should be avoided in polite or professional settings.

Examples

Have you gone crazy? Why are you saying such things?
He is always losing his temper, acting like he has lost his mind.

Common mistake

Do not use this literally to describe the act of eating feces, as it is strictly used as an idiomatic expression for mental instability or foolish behavior. Using it in a serious context will cause significant offense.
