We have better slang over here.
I always find it hilariously that the chavs (who are remarkably racist) go around trying to speak like black rappers. You're paler than most fucking goths, lads: that isn't going to convince anybody. At least if they spoke like a proper British wide boy the high pitched squeaky delivery would be less obtrusive. (I really hope the suggestion I heard that the stupid little twats do that because they think it makes them sound like they've been autotuned isn't on the level, but they probably are stupid enough to try to fake that, sadly...)
You know the 'gangster' kids on the estates here refer to the police as 'the feds'? God that makes me wince. It's embarrassing.
Do they do so in a affected castrato shriek and a fake sarf lahndahn accent as well?
I was thinking of the SE London kids, in fact - that's where I spent my twenties. The gangsta kids around Bristol, where I am now, aren't even intelligible to me.
