UPDATE: The context of his Twitter feed shows 50 Cent was joking about straight men only; as I explain in the comments of this post, I do think it was a careless thing to say as context doesn't travel. And "Lol" doesn't wipe everything away. But 50 Cent has clarified (not apologized) with some new tweets and reiterates his mother's lesbianism.
"It Gets Better," but not if this bullet-magnet has anything to say about it. Perhaps 50 Cent's tweet was more to scold heterosexual men who refuse to go down on a woman but expect their women to do [insert anything sexual you can think of, even jokingly, here]. But it's still gross.
