When a male has sweaty testicles and pelvis thrust forward and backward causing his sweaty testicles to make a “slapping” noise. Preferably done right out of the shower in only a towel.
Sam walked out of the shower in a towel with a crazed look in his eyes, and moved his hips back and forth rapidly creating a loud slapping noise. He was performing a powerful swingset.

A sexual position, similar to the Bonesaw, in which two women and one man is involved. The man, wearing a strap-on on his ass, stands between two tables with women lying on them, face up. With the women's legs on the man's shoulders, he proceeds to penetrate forwards, and backwards, therefore boning both women simultaneously.
Dude! I ran the swingset on those two hoes last night!!
