A classy chav, usually someone trying to deny their chavness but they just can't resist wearing the odd bit of cheap bling, bright white trainers or going happy slapping with their pit bull.
I hate Clavs. Danielle Westbrook, Ashley Cole - stop denying yourselves, you might as well just buy yourselves a vauxhall nova and have done with it.
Warning to all you ladies out there this is important street survival information. When a guy or gal compliments you on your clavicles they are literally saying that your tits are the fucking worst. Its a new thing going round that guys are now doing so be on gaurd
Though if it does happen to you then you must have shit tits, so let's hope you have a nice ass
