An enormously fat woman with a fupa so large if you put a wig on it you might mistake it for a siamese twin. They usually date or marry scrawny guys with bad mustaches.
My aunt Paula is a classic example of a fupapottamus. Legend has it she has extra elastic material sewn right below the zipper of her pants to comfortably house the fupa. Her measurements are 48-44-46-52. The last measurement is proof she is a fupappotamus
