Ramadan: Is it haram to be gangsta?

LOL, in what sense? Are you talking wearing the style and using the lingo (like the grammatical things, not the swearing and such)? In that case, I'm pretty sure it's not. There are "gangsta rappers" who proclaim themselves to follow Islam. If you're talking about the drugs, sex, and "drive by" deeds, then I'm pretty sure that goes against any religion. XD
