Newton’s Cradle 

A modified spit roast. One guy’s dick in the girl’s mouth, the other guy’s dick in her pussy/ass. When one guy thrusts in, the other pulls out, and vice versa, so it looks like a Newton’s Cradle.

“Man, Sally’s such a slut.”
“Yeah, she let Tom and I give her a Newton’s Cradle last night.”

Newton’s Cradle 

When a male is standing feet apart, and another male is standing behind tries to slap your butt, but instead his fingers come upon impact to a single testicle, which in turn Newton's cradle demonstrates the third law of motion. When one of the balls is lifted and released, it strikes the remaining stationary balls and sends force through all of them to push the ball on the other end away.

David stood behind Chris in Nanoom, attempting to slap his butt, however David accidentally missed Chris’s cheeks and his finger managed to hit a single testicle, resulting in a “Newton’s Cradle “.

Newton's Cradle

Newton's Cradle refers to a girls crotch when she has skinny thighs so they do not touch each other when she is standing up.

This phenomenon enables you to tag her from behind, allowing your balls to swing freely between her legs without touching them, tapping the front of her, like the famed executive ball clicker --- the Newton's Cradle.

She was in really good shape, a total Newton's Cradle.
