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.
