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!

Spermathon

When your sperm do 42 (micro) kilometres for their chosen charity(s).

How did your little guys do at the Spermathon earlier bro?
