The act of shitting and Masterbating together; The Ultimate Time Saver
I only have 3 minutes, I have to shiterbate or else I wont have time.
To go to the restroom, informing everyone you intend to take a shit, and remain in the restroom for an extended period of time while actually masterbating
Scott: Where is Kevin?
Andy: Oh he is in the bathroom, has been for 20 minutes, said he was taking a shit.
Scott: Oh, he must be going to shiterbate.
