Chicken Run Syndrome 

A genetic abnormality affecting a large number of women in modernized nations. Mainly features a large and overweight midsection/upper thighs while the remainder of the physique is still fit in nature.

Not a lot can be done to rectify this and it is a shame when an otherwise hot girl has been afflicted.

Refer to the movie chicken run for visual examples.
