While taking a massive shit, you get a NRB (No Reason Boner), and you decide to wack off.
Blinke- "Hey Casey! Have you ever tried to take a masturshit?"

Casey- "No man, thats just gross."

Blinke- "Oh, but it feels so great."

Get the Masturshit mug.
Masturbating while sitting on the toilet taking a shit to save time.
I had to leave the house in 15 minutes so i masturshitted and killed two birds with one stone.
