How it's used

Refers specifically to male genitalia in a vulgar or derogatory context. It is rarely used to describe the anatomy itself, but rather functions as a crude way to dismiss someone's speech as lewd, inappropriate, or purely focused on sexual topics. The term carries a strong sense of disdain for the speaker's lack of decorum.

Examples

Common phrases

to talk dirty or lewdly

Common mistake

Do not confuse this with the common phrase 講是非, which means to gossip or stir up trouble. While they share the character 是非, the addition of 根 changes the meaning entirely to a vulgar anatomical reference.
