black hole crotch 

A situation where the fabric of shorts is drawn into the crotch area, sucking it inward as a black hole sucks in matter. Most frequently occurs between the legs of heavier women, often those wearing short shorts or shorts that are just a little too small. As the wearer walks, the friction of the legs being rubbed together pushes the fabric upwards, resulting in black hole crotch.
Black hole crotch is frequently accompanied by overexposure of thighs, often riddled with cellulite and stretch marks.

Oh God, that woman had to be over 300 pounds! Why was she wearing short shorts? I think that was the worst case of black hole crotch I've ever seen...
