Seriously though, I have no clue what a "chav" is. XD
A chav is part of a group of chavs who are all social degenerates and have single handedly given burberry caps and fcuk t-shirts a bad name with their wanton acts of violence and criminal damage. They truly are a plague on society.

I imagine the Chav to be the english equivalent of the American Inbred Hillbilly. Like Cletus the slack jawed yokel.
