this is for us brits as I doubt you yanks will get much of what I am going to say!
I personally like them, as I think they are just taking the piss out of chavs. Alot of people think they are really like how they act (chav-like) but I dont think they are like that to be honest. Then again I could be totally wrong and they may actually be chavs, in which case they arent that funny, just gay!
And for you yanks...do you actually know what they are taking the piss out of, chavs? Or do you find them funny for a totally different reason?
