every region has there own name for them. charvers has been in use around the north east for a very long time, i was using it back in the 80s so its at least that old, i would guess much older. i dont know why the chav word was so readily adopted nationwide or if it is related to the charver word (probably is), the press picked up on it and now its in the dictionary!
when i first went to uni in 99 i noticed that everyone had thier own name for charvers (and everything really). pikey was quiet a common one that was used by people from scotland and the midlands. towney is also common across the UK. but charver is purely a north east thing and we still use it more than chav. i hate it when people say chav, ITS CHARVER!!! and always will be, the new monkey posse told me so. (oi oi whistle posse, mc smakhed on tha mic, ooa ooa)
but more importantly, when did they start putting their trakky B's into their socks? and why? it looks so gay i want to hit them when i see it, and i still would if i wasn't too old to get away with it.
