A person who A) Wears tracksuits at all times, fake Burberry caps, gold jewellry (the chunkier and less tasteful the better) rolls their trouser legs up to reveal their ankles/pulls their socks up over their trouser legs; if female has a bottled tan, large hoop earrings, hair tied up rediculously tight so as to actually distort the natural shape of their face.
B)Hangs around on estates, parks, high streets, outside McDonalds or in childrens playgrounds whilst drinking White Lightning cider, gossiping about either East Enders, Coronation Street, I'm a Celebrity..., the ugly swine they got off with the night before or how 4 of them beat the crap out of a lone "Greebo/Grunger"
C) Has a self imposed inabilty to say words of more than two sylables, brought about by purposefully ignoring all attempts by the State to educate them.
The most common example to be easily found of a Chav is outside your local McDonalds, or in the nearest park, sitting around the bench closest to the football pitch(if one is present).
Celebrity examples of the breed include Wayne Rooney, and Mel C.
