I'm becoming increasingly convinced that The Chav is an urban(e) myth. I mean people like this couldn't really exist in dear ole blighty?[/quote
In Spain to be called a Chav is a good thing. It is used in the way Brits use mate.
It's a slang word derived from the ancient gypsy language for a young man.
'Oi chaval have you got a cigarette' is not at all an unusual phrase to hear. An answer of f*** off and buy your own wouldn't go down well.
