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
An oversized woman who prays on drunk men in social settings. The fuckapotimi are attrackted to men with slured speach, and impaired walking abilities. The attack is known as being grizzlesnatched.
