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.
Examples
He is so treacherous, who would dare to do business with him?
You must never be a traitor and betray your own brothers.

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.
