I'm gonna go ahead and say "*****".

People who feel it's acceptable to use this phrase are very dumb. It's racist. Unless you're in a one-on-one conversation with a black person you know well, and it's jocular racism that's ok by them, it's unacceptable to have as vocabulary.

Especially when girls who aren't black say it. That's the worst. That goes back to girls who think they're ghetto though.
