The thing is, you say you ain't a chav, but you say you have a "gang". I bet you wander round the streets at night causing trouble, or manage to get yourself into trouble somehow (I bet it's not your fault though...). Whether or not you are trying, I bet you and your "gang" are very intimidating to some people, and that's just plain chav. It's people like you who make some parts of this country feel really unsafe to walk around. Don't try and justify it.
If I'm wrong and your "gang" is inside playing Warhammer every evening then I apologise.
