Perpfisting is practically the most revolting form of fisting possible.

You take a perp, roll him in pine pitch and river gravel. You then lash him to the business end of a catapult or trebuchet, set the apparatus to fire, and then position the girl carefully spread-eagle in front of it. The perp should have at least 6 feet of rope tied to one of his legs.

When the catapult/trebuchet fires, the perp is then energetically forced into one or both of the girl's lower orifices. To get him out, you just pull the rope tied to his leg.
Perpfisting is a fine way to spend lazy gray Thursday afternoons.
