How it's used
While this term directly translates to madman, it is frequently used as a harsh insult to describe someone acting irrationally or dangerously. It carries a much stronger, more aggressive tone than simply calling someone silly or weird. Using it to describe someone with actual mental health issues is considered highly offensive and derogatory in modern society.

Common mistake
Avoid using this word to describe someone who is just being eccentric or silly, as it carries a heavy implication of losing touch with reality or being dangerous. In casual conversation, people often prefer using 黐線 to describe someone acting crazy.
