A form of genitalia that is similar to a penis. It shoots out shit and shoots solid cum. Only a few people in the world have them and when they touch someone else they lose their poonis and pass it on to the person they touched.

Half Penis, Half Poon, Poonis. That is what a hermaphrodite has. I thought of this word first David, you bastard.

What you get after fucking a guy in the ass when he hasn't taken a dump in a few days. A Penis covered in Poo.

Billy: first mate reporting for duty!
Grandpa: 'tis a fine instrument you got there, Billy. All hands on the poop deck.
Billy: oh Gramps. Here it comes...
Grandpa: garrrrrrrrrrrrrrrrrrr. That's the stuff.
10 minutes later:
Billy: awwwwww - sick. Grandpa, I have a Poonis.
Grandpa: yarrrr. Gross. Time for a colostomy bag...
