Motor Beering

A hybrid of Motor Boating and a Body Shot. Beer is poured into the cleavage of the Motor Boat recipient as their jugs are simultaneously being mouth jiggled.

motor bagging

A cross between motorboating and tea bagging. When two guys stand close together with legs spread, and a third person gets under them and motorboats their ball sacks.
