spermathon 

A ridiculous challenge between male friends to determine who can ejaculate the most times within 24 hours.

Guy 1: I bet you guys can only jack off twice before you can't anymore!

Guy 2: Why don't we have a spermathon to determine who can do it the most!

Spermatozoan

Spermatozoan is just a fancy word for Sperm which are the reproductive cells contained within the Semen that a man ejaculates when having sexual intercourse with a woman thus leading to fertilization of said women which ends up in the absolute Fuckery that is birth, so now we are all doomed to the fate of existence and Fortnite.

We were all Spermatozoan at some point but now we are just fucked!

Spermatoast

A meal prepared by sreading peanut-butter and jelly on a piece of toast then ejaculating on said toast.

Dude my girlfriend woke me up in the middle of the night to make her a sandwich, so I made her some Spermatoast.
