Wang Lang

Wang Lang, courtesy name Jingxing, was a politician and minor warlord who lived in the late Eastern Han Dynasty. He became a politician in the state of Cao Wei during the Three Kingdoms period after the fall of the Han Dynasty.
But his first name is Lang and his last name is wang, which sounds like a long penis....

A NPC (Non-Playable character) in a computer game that keeps screwing up your game plan, and runs around like an arsehole. Especially applicable to anyone particularly annoying on Dynasty Warriors.
