Blind Cyclops
Most commonly this happens early in the morning for men, especially after a night of sex, but could happen just by sitting in one position for too long. This is when you go the pee, and it shoots off to one side or pulls a "Y" effect and sprays on the toilet seat instead of getting into the bowl.
Oh man, I have a blind cyclops. I just got pee all over the seat.
Blinded Cyclops
When a woman is giving a man head and right before he nuts, she aims his dick back at him and shoots him in the eye.
I got Jeff back for cheating on me. I gave him a blinded cyclops when I was going down on him and kicked him in the balls.
