When you get a girl to half squat and fist her ass, but as you are fisting her you use the suction that your fist pumps create to loosen her bowels onto the floor. Or, if performing the "Korean Slugepump", you get her to release them onto your stomach and genitals.
'I have a hefty doctor bill to pay for the rediculous Sludgepump that i preformed on a transexual stripper last night.'
'Boy tom, is it ever hard to wash feces out of your ballhair after you admister a real good Korean Sludgepump.'
