How it's used
Often used in the reduplicated form 瘋瘋癲癲 to describe someone acting in an erratic, hyperactive, or unpredictable manner. It carries a slightly playful or exasperated tone rather than a clinical diagnosis of mental illness. When used to describe someone's personality, it suggests they are eccentric or lacking self-control in social situations.
Examples
He is always acting crazy, it is really hard to deal with.

Common phrases

Common mistake
Avoid using this to describe someone with an actual mental health condition, as it can be perceived as offensive or insensitive. Use 傻 or 黐線 instead if you are trying to express that someone is acting foolishly or irrationally in a casual context.
