When you nut but miss your target and the nut flies across the room never to be found again, probably consumed by the Semen Demon
I accidentally nutted on my floor and couldn't find it to clean it up. I think the semen demon took it.

When a guy hasn’t nutted in a while and he starts to not think clearly. He’s possessed by the semen demon.
Chuck though about calling up his hoe x cause he had the semen demon whispering in his ear. After he spanked it though he knew that was a bad choice.
