Missouri Newton's Cradle

The Missouri Newton's Cradle is an activity in which 4 or more men tie a rope or string with a weight around their scrotum. They line up, generally close together and facing one direction, and the one in the front pulls their weight forward and releases it so it hits the weight behind his. This will go on to the last person and then you have completed the Missouri Newton's Cradle.

Have you seen Josh, he has been walking funny ever since he took 50 pounds at last night's Missouri 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.

Newton's Cradle

A two-man variation on 'teabagging' in which the four testicles represent the swinging balls of a Newton's Cradle. The slapping of the two scrotal sacs together in an approximation of the cradle motion is optional, if physically achievable.

Joe was so wasted, we took about 30 pictures of him getting a Newton's Cradle while he was passed out.
