Semen Monster

After you cum, the uncleaned semen group together to form a chunky piece of shit -the Semen Monster. The leftover semen can come from a variety of places: laptops, bathrooms, tissue paper, vaginas, even your belly button. As the Semen Monsters multiply, they scheme to take over all vaginas, and pollute our offspring with semen DNA. Nasty stuff!

Timothy: Hey, just finished jacking it.
Lancelot: Ooh, better clean your junk, the coagulated semen might group together and burst out of your cock and turn into a Semen Monster.
Timothy: Just like in Alien?
Lancelot: Just like in Alien.
