Potamus- That girl that you took one for the team for, back in high school before you took off your training wheels; you know a lil old “nail the whale”. They are also notoriously known as savage individuals whose only concern is to consume large amounts of semen into any orifice on their body. They are always that “thing” that stares at you like you’re an appetizer and insists on talking to you at the bar and making awkward sexual advances towards you. Sometimes Potamuses travel in small packs consisting of 3-4, they hope to increase their odds of mating with attractive men in the NAVY such as myself. They are extremely dangerous exercise caution as needed.. They can also play defense for attractive females at the bar, especially when it is near last call for alcohol; every man’s mad dash for take home pussy might be thwarted by a vindictive potamus. Be warned, and stay thirsty my friends!
Example: See Cockblocker:

Man- Hi there, my names Tom!
Attractive female- Oh hello, im Sta( interrupted buy loud potamus shriek; sounds like an angry wildabeast/ape grunt thing).
Man- Throws a dog treat to get rid of potamus.
Attractive female: anyways I need a ride home.
Man: Score! Man one potamus none!

Added to the end of a word in a sentence to aware listeners about your obsession of hippopotamuses.

Another use of potamus is by itself as a word for the person you are talking to.
Give me a pencilpotamus.
Get out of my house, potamus.

A sex act involving two men and a woman. During double-anal penetration (both men putting their "Peter" in her "Potamus"), the woman starts a low howl; she is then joined by both men as their vocalizations evolve into a Hippo Hurricane Holler, which lasts either until both men ejaculate inside her or the three start laughing so much as to make sex impracticable.

Based on the cartoon character Peter Potamus, inspired by a misheard lyric from "3," the Britney Spears song about guy-guy-girl sex -- instead of "One, two, three / Peter, Paul & Mary," the listener heard "One, two, three / Peter Potamus me."
Dude: Bro, what happened last night?

Bro: Dude, I can't believe you don't remember! You and I righteously peter potamused that chick from the party.

Dude: Awesome, bro! Did we make it through, or break up laughing again?
