Knuckle dragger

A narrow minded person often dressed in Burberry who eats curry and complains about Paki’s. They travel in packs and have large shiny foreheads and slopping posture.

The female of the species can be found with greasy hair pushing a pram and screaming at any one of its five kids.They are most likely found in a small town called Bedworth (or beduff as it is know round here), famous for producing Pete Doherty
