50 Cent is becoming Twitter's biggest bully. Despite announcing a self-imposed, week-long hiatus to work on his new album, Fiddy resurfaced this afternoon poke fun at Atlanta rapper T.I. The "King of the South" was arrested in West Hollywood last night, after pulling an illegal U-turn while driving with his wife Tiny, and charged with felony possession of a controlled substance, including pills believed to be ecstasy.

T.I.'s latest arrest drew 50 to post a clip from 'Menace II Society,' where the detective interrogates Caine, saying "You done f---ed up, you know that don't you."

"Damn TI damn! u the king damn! lol," 50 exclaimed in the accompanying caption.

Meanwhile, T.I. is attempting to remain optimistic about the pending charges, according to his lawyer. "There may be no severity to this matter at all. There may not be any validity to this matter at all. So I think the best thing for us to do is to adequately investigate the circumstances and the facts and remain optimistic that whatever has happened will be favorably resolved."

Rappers got cases, 50 got jokes.
