Chav being your average burberry clad 106/corsa/fiesta/clio driving lanky little bum boy that kits the whole car out in ripspeed bolt on tat such as "motorsport" sunstrips, stick on "aluminium" petrol caps, ripspeed 5" exhaust tips, 17" alloys on said clio's/106's etc that have a 1.2 engine or smaller (with a max power induction kit) without lowering them, lexarse lights, led washer jets, burberry neons (if they could!) etc.
You get the idea!? I know thats a little harsh on some as they genuinely can't help it, but hopefully they will realise one day!
