Master-poo

-The lost art of simultaneously pounding out one's own ejaculate and feces into the same receptacle.

-The time-biding act of gratifying oneself while defecation occurs.

After Chauncey saw the sexy broad on his way to the bathroom, he knew the Sun-Times was not necessary as a master-poo was now in order.

masterbortion

an instance where one has been masturbating alone in his/her house and is approaching climax, and has to stop because mom came home and she wants you to bring in the groceries or take up your time in some other lame way that resembles the opposite of orgasm.

I was jerking off to a UFC fight but had a masterbortion when my mother came home and made him plumb a turd out of the toilet.
