The sexual art of picking up your girlfriend/sister over your head, much like a giant, and bringing her back down forcefully on your knee. This act is properly done when the back is not broken, but your female partner is short of breath and gasping for air. You can make it extra fun by orally fucking her senseless as she gasps and sputters for air.

The subject must be at least 6 foot tall for this term to be used. It occurs when one male of at least 6 feet in height is dancing typical Caucasian moves with a newly acquainted female counterpart, and then an even taller male rudely jumps in between the two with spastic, over-the-top "Night At The Roxbury" moves resulting in the aforementioned male being cast aside to either the left or right of the female wondering what the fuck just happened.

This happened to me last night at a dance club and I immediately coined the phrase due to my sharp wit and ability to straight clown someone that cockblocks me.
