When you bash your meat so fast and hard that you leak out a thick, hot load of cum like you just got out of a meat grinder.
I did this in the bathroom at work and my coworker heard it. He called me a cum machine.
My brother did this during a video game battle. He got a warm load and a victory.
My friend did this at a party and got a warm load on his pants. Everyone laughed.
