How it's used

Originating from traditional Chinese medicine and folklore, the term refers to a protruding bone at the back of the skull that supposedly indicated a rebellious or untrustworthy nature. It carries a strong negative moral judgment, implying a fundamental character flaw rather than just a single mistake. It is frequently used to describe someone who turns against their own group or benefactor.

Common phrases

a treacherous person

Common mistake

Do not use this to describe someone who is simply disagreeing with you or being stubborn. It specifically implies a betrayal of trust or loyalty, making it a very harsh accusation that can easily cause offense.
