Person conceived of breeding between
two closely related couples, or someone with a very
weak gene pool, but usually the former. Places famous for being rather inbred are some remote or scummy parts of the
UK (where the chav population is high) and US redneck areas. This is a great
shame for both countries as both have a typically wide gene pool due to different peoples settling over many hundreds of years. Also, royal circles are rather inbred too, for legitimacy reasons.
