灰太狼的知己叫光头强
[huī tài láng de zhī jĭ jiào guāng tóu qiáng]
Refers to characters from a popular Chinese cartoon 'Pleasant Goat and Big Big Wolf.' Here, the user humorously pairs a character (Huí Tàiláng - the wolf) with Guangtou Qiang, who are traditionally portrayed as adversaries but implies an unexpected or humorous friendship.
