butt fish
(verb): sperm that live in the anal cavity after being deposited by the donor along with seminal fluids through anal sex. They remain in the rectum swimming around, occasionally swimming out of the anus and often being pushed out by feces. They can live inside the host/hostess's body for three to five weeks before they die, often of malnourishment. They are carniverous, eating other sperm, until one "fish" becomes the dominant head. Though harmless, besides the occasional constipation, butt fish can become an embarrassment and the subject of constant joking and mockery towards the individual who acted as the host.
Green Lantern: Did you hear that Wonderwoman had butt fish?
Wolverine: Haha, no way, who gave them to her?
Flash: I heard it was Superman, he boned her so hard she won't shit for weeks!
