How it's used
This expression uses the imagery of a main electrical switch shorting out to describe someone acting erratically or losing their temper. It carries a stronger, more vivid sense of sudden, irrational behavior compared to the more common 黐線. It is frequently used in arguments or when someone is baffled by another person's bizarre actions.
Examples
Are you crazy? Why are you acting out of nowhere?
He always says such nonsense, he is truly insane.

Common mistake
Do not use this in formal settings or with people you do not know well, as it is quite blunt and can be perceived as an insult. It is strictly for casual, heated, or joking interactions between friends.
