A portmanteau of the two words "poop" and "vagina"; It describes someone known as a poop-vagina, which is basically, for lack of a better word, a girl who fucked a guy who fucked a guy's butt.

The word describes the transitivity of the poop from the person who "took it" through the medium to the girl who received the "poopy wiener"
Ben: Hey did you hear Jessica was a poo-gi?
Jerry: A what?
Ben: You know, ever since she fucked Adam, she's been a poo-gi.
Jerry: WHAT?!
Ben: Man, don't you ever read urban dictionary? You piss me the fuck off. This friendship is over.

Get the Poo-gi mug.
A clever combination of the two words (a portmanteau if you will, of) "poop" and "vagina"; It describes someone known as a poop-vagina, which is basically, for lack of a better word, a girl who fucked a guy who fucked another guy's butt.

The word describes the transitivity of the poop from the person who "took it" through the medium, who we will call an Adam, to the girl who received the "poopy wiener."
Bill: Hey did you hear Jessica was a poo-gi?
Ted: A what?
Bill: You know, ever since she fucked Adam, she's been a poo-gi.
Ted: WHAT?!
Bill: Man, don't you ever read urban dictionary? You piss me the fuck off. This friendship is over.
