occurs between two people.
First: person A stretches out person B's anal canal by inserting
the middle finger, index finger, and thumb into the bum- and spreads the fingers.
Once anal hole is stretched:
person A inserts the head of a mop- preferably new- part with threadsinto person B's bowels, jiggles mop in order to clean person B's colon.
And that, my dear friends, is
the ULTIMATE chimney sweep.
