Ok this is my problem:

I am looking for a word X that fits into this scenario:

Dude1: "What's a chav?"
Dude2: "It's the Brittish term for X"

Now I seem to remember that word X is very common, but I can't remember it at all. Can you help me?

I would think that it depends on where you live as to what you relate it to. Even within the UK every area basically has their own names.

A chav is a chav. You'll have to show them pictures of chavs to get the message across. The closest US term I can think of is "white trash", but that doesn't really account for fashion side of chavism.

darn! maybe i've just gone mad. I seem to think that word X is used a lot, it's annoying me now...

for those who are totally " " see http://www.chavscum.co.uk

Thankyou I was lol

I would say "gino" but again, that depends on where you are

Wikipedia knows all!

Ned, Townie, wank3r... plenty of different names

"It's the British term for a chav."

Seriously, there's no other way to describe a chav. A chav is a chav. Plain and simple.
