Soicsturbation 

A big ginger guy rubbin a fat one. Most likely a soic. Perhaps even slobbing on it.

Soic did a soicsturbation stream on twitch yesterday. All he did was soicsturbait for 11 straight hours. So much blood.

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.

Sawyer: Ewwww gross!

Garrett: It's just Simsturbation.

Omenchild: Oh well in that case it's fine.
