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

someone from boston, lincolnshire.
