Lets clear up what a chav is.
1) A chav prefers Cider to Beer, and they always drink it at parks.
2) Reebok is a godsend
3) Out with tartan check, in with Burbury
4) You can never have enough gold
5) Tracksuits are a must have
6) Chavs never tie there shoelaces, always tuck them in
7) Getting a tiny bit of dirt on you is a disaster
8) Your always think your great
9) Music has to be loud (although it really does in my opinion
10) You might aswell not have a car unless a) It has atleast 1 Kenwood 12" Subwoofer, b) It has something hanging down from rearview mirror c) It must have a spoiler and bosy kit
11) Smokeing 1 cigarette is not going to hurt you
12) Weed isnt adictive
So there you have it, a list of rules a chav must follow, although some chavs do not meet them requirements.
P.S.
Doing up your car can be fine, just has to be the right make/brand.
