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.
