How it's used

This term is a specific piece of Cantonese slang derived from the English word insane. It is used to describe someone acting erratically or behaving in a way that defies logic. While it functions as an adjective, it is frequently used as a noun to label someone as a lunatic.

Common mistake

Do not confuse this with the word for kidney, which is also written as 腎. The slang usage is strictly phonological and has no connection to the organ.
