Chav = Young british person who comes from a poor, working class background, believes he is god's gift to everything. He also (if old enough) drives an old either Nova or old Ford Fiesta that looks crap, but has a way too expensive sound system in it, an induction kit, alloys etc etc. Oh and he proceeds to drive around town at bout 2am wasting all his petrol and playing some crap garage music way too loud.
Alternatively stop being lazy and go to www.chavscum.co.uk as tango said earlier. They really are the bane of my existance. And i live in an area full of the little pikey shits. Bastards all of them.
In response to MeatFarts, no we don't have a 5 button mouse, but we do have a 3-button mouse.
