When one "mate" shits in aluminum foil, places it in the freezer, or out side on a cold day, and inserts it in to the other "mates" rectal area to perform pleasure.  The frozen piece of tundra replaces the old dildo for something more jagged and cool.  *hint: try eating corn, peanuts, and fiber before defecating into the foil for extra ribbed.  This maneuver can also be performed solo.
Ben was tired of the traditional dildo in his ass, so he convinced Josh to give him an alaskan pipeline instead. So that morning, Josh took a dumb in aluminum foil, froze it, and had hours of fun when they got off work.
