There are a select few of non-chavs, who were brought up as middle class people so refuse to associate themselves with teh chavs, and will often not even refer to Mitcham as their hometown. The chavs hate these people and as they're driving past KFC and the pound shop in their Range Rovers and Porsche's, the chavs look on with envious, jealous and evil eyes, thinking of some lame insult that probably means nothing to the average person. You see, you have to be special to understand chav. Really, really special. And not in the good way.
Middle Class Person: Oh, I'm from Surrey.
Chav From Same Town as Middle Class Person: Nah, brav, swear down mandem's seen you jammin' in mitchum Mitcham.
Middle Class Person: *shifty eyes* You must be mistaken, my *cough* friend.
Chav: Brav, look at dem pooosies jummin past in dem flasj cars, dem mandems are moiiiiist.
