In the US, inbred's usually play banjos, wear dungarees and are hillbilly's
Here in the UK, many places are quite inbred. I moved to a notoriously inbred area a few years ago, and the people here are all
simpletons, look really gaumless and usually come from the old, long-established fishing families. Most of them are special or disabled in some form or another. Physically, they have protruding ears and close-together, slitty
squinty eyes, a flat, screwed-up face like a scrotum and dirty teeth. For some groups of people, such as chavs and pikeys/gypsies/
travellers, and farmers, and the Welsh.
The offical meaning of an inbred is someone whose parents are related to each other, or one of their parents is inbred, or granparents
