An obese mammal that has been mentally castrated by a woman of questionable morality. Not to be confused with pussy-whipped, where the aforementioned mammal actually gets pussy.
"I can't believe that pussopotamus let her draw all over him while he was sleeping and didn't have the nerve to retaliate."

The pussopotamus may sleep over at her house, but he sleeps at the foot of the bed.
