What DOES chav mean.
I have seen middle class chavs at uni, they just wear a higher brand of clothes than the tracksuit ones, some have the bling some dont.
To me chav is a mentality not a social background thing, I have seen some really chavvy guys in big brand clothes but sound and act like chavs but their behaviour is tolerated by people when if a poorer one did it its not ok, seen guys in bars act this way and the girls are all over them, but if a traditional chav does the same they act like the chav is below them.
