Shitsturbation 

A simultaneous performance of shitting and masturbating, often done in public restrooms.

Kayla: Wow, I heard some really weird noises when I was using the restroom. Sounded like someone was really enjoying their dump...
Michael: They were probably undergoing Shitsturbation. It's like a self-performed blumpkin with your hands.
