When a man is on a swing, gaining momentum, and the woman is on the ground in front of the man bent over. The man then swings down and taps her ass and then swings back, and then when he swings forward again, tapping her ass, and doing so over and over again.
Joe used the pendulum on me so hard on the playground yesterday.
