Depends what you mean by chav
I have a personal near-hysterical loathing for the term because it seems to mean anything between "teenagers who have sex and wear shit clothes and listen to shit music" (i.e. "teenagers") and "the people who mugged me for my telephone and rape babies in council flats"

i agree
a 'chav' is someone who 'dresses above their station.

When most people say 'chav' they actually mean 'binner', 'scrubber', or 'pikey'
