when the girl lays on her back and BOTH legs are behind her head & then you know what happens!

when having sexual relation in the doggy style position the man reachs his hands between her arms locking his fingers together on the back of her neck and pulling back with great force.

The act of anal rape.

during sex, doggiestyle of course, slipping two (or three) fingers in her butt, and picking her up off the ground and/or bed whilest screaming "HUCKLEBUCK!!!"

Jennifer or Amanda leaves the Pub drunk. They feel sorry for their date so they decide to give it up. Next thing they know they are in the hucklebuck and somebody yells "donkeypunch". Not being their first time they stopped dropped and rolled and punched the young man in the back of the head. Thus inventing the reverse donkeypunch.

A confrontation. When somone calls you out.

The girl is on her back with her heels on the back of his neck. He is standing with his arms wrapped around her shoulders. And then she screams "Hucklebuck!"
