The pain between the legs that women feel from the seat on a bicycle, or after a spin class. Kelly Ripa brought attention to this word by using it on a "Late Night With Jimmy Fallon" episode.
Female genitals engulfed by fat, such that the stomach area of the woman just rolls down into the vaginal area. Fat like a hippopotamus. Hipposcrotamus version for the male.
That lady was so fat, I sure wouldn't want to see her vagapotamus.
