Hah, I use the term ghetto often. I'm not referring to people with any certain color skin, though. To me it's more about attitude. One that promotes violence and general bad-assed-ness as opposed to calm discussion and a more humble way of being. I've had quite a few friends who had a ghetto mentality. It really disturbed me that when someone did something unfavorable to them, their response was usually something like "I'll go kick her fucking ass, me and my sister will go fuck her up and beat her face in" instead of something more reasonable.
But yeah that video is funny. It could be made for all sorts of people and things they say to others, not just white/black.
