An action in which you place the penis and both testicles inside the oral cavity of a reciever, plug their nose, and a glorious suction sensation will occur. Move their head back and forth vigorously, like you would a plunger, minding the nose plug. If crying or a look of uneasiness overcomes your patient, it means there hasn't been enough violent pounding.
Person 1: What was the coolest thing you've ever done with a chick?
Person 2: Probably the time I gave that huge slut back in Vegas the plunger.
Person 1: Oh yeah, that was awesome.
