cosmopotamus 

A highly prevalent subspecies of the cosmetician family, which is characterized by it's robust physical stature, known colloquially as the fat hairdressers. Often seen wearing mostly black.

This morning I witnessed the migration of a group of immature cosmopotamuses as they navigated their way down the alley to the hair dresser school.

Cockopotamus 

One who is so slutty that they are filled so full of cock that they become the size of a hippopotamus. Can apply to both male and female and is only to be used on the sluttiest of people.

Ashley is such a slut, she slept with the whole damn school, what a cockopotamus.

cockopotamus 

A cockopotamus was the result of a science experiment gone wrong in 1776. The experiment created a new species called the "cockopotamus" which is a mix breed between a penis and a hippopotamus resulting in the shape, size, and color of a human penis, with the size of an entire hippopotamus.

That slut, Jake L*bella just got fucked by a cockopotamus!
