How it's used

Used as both an adjective to describe someone behaving irrationally and as an interjection to express disbelief or annoyance. It is extremely common in casual settings but should be avoided in professional or formal environments. When used as an interjection, it often carries a tone of exasperation or playful shock.

Examples

What are you doing, are you crazy?

Common phrases

acting silly or dazed

Common mistake

Do not use this to describe someone with a clinical mental health condition, as it is strictly colloquial slang for eccentric or irrational behavior. Using it in a serious context can be perceived as highly offensive.
