A man puts on three strap-ons; one on each side and one on the back. He then stands in the center of four bent-over women and has sex with them all at the same time by moving his hips in a circular motion; as if he was hula hooping.
Optional: Can be done to the tune of "Jump On It" by Sir Mix-A-Lot
Dude, I got with four chicks last night and we were totally hula hooping!
(verb)
1. The act of convincing yourself that the hula hoop is going to stay up this time, despite a long and well-documented history of it immediately crashing to the ground.
2. Maintaining unreasonable optimism while your waist, hips, and the laws of physics negotiate behind your back.
