How it's used
Beyond the literal meaning of mental illness, this word is frequently used as a hyperbolic exclamation to describe someone acting in an absurd, reckless, or highly irrational manner. It often functions as an adjective to label behavior that deviates from social norms or expectations. When used in the reduplicated form 癲癲得得, it carries a softer, more playful tone suggesting someone is being silly or flighty rather than genuinely deranged.
Examples
Are you crazy? Why are you throwing everything away for no reason?
He is always acting erratic, it is really hard to communicate with him.

Common mistake
Do not use this word to describe someone with a clinical mental health condition in a serious or professional context, as it is considered offensive and derogatory. It is strictly a colloquial term for informal social interactions.
