灰太狼我给你羊
[huī tài láng wŏ jĭ nĭ yáng]
Derived from a popular animated series where 'Huí Tàiláng' (Woolly Big Gray Wolf, character name: Hútai Láng 灰太狼) always wants to catch a sheep ('羊' yang) for his plan or meals. The username humorously refers to someone handing over or making something easier for another person (or enemy). It also plays into the cartoon characters.
