Well, before the advent of the word chav my friend and I invented a name for them. We used to use the prefix Bo, (as in bo selecta- but this was before the program, we truly were visionaries) it works with anything, observe;
"Hahaha, look at that bo-child"
"That bo-guy looks like an idiot with his tracksuit bottoms tucked into his socks"
See? I'm so glad I could finally share that with the world...
