knee-butt

The knee-butt is a painful yet entertaining move that can be preformed on friends and ememies alike. The move is executed as follows:

The unsuspecting victim is standing so that their back is facing you. Approach the person, call out "knee-butt!" and knee them right in the ass bone. Hurts like hell. It is customary to call out the knee-butt warning before kneeing. When knee-butting friends it is recommended to knee with care, due to the potential anal crushing power of the move. Grabbing onto the persons shoulders can add a more visually dramatic element to the move, as well as increasing the power behind it.

Kevin: "Dude why are you hopping around and holding onto your ass like a fucking fairy?"
Steve: "Dustin just friggin gave me the worst knee-butt of my life!"

Knee-Butter

The build-up of sweat and dead skin congealed into a buttery substance. Generally found within deep fat crevices i.e. - knee or elbow area.

It's so hot out, I could slather a whole loaf of bread with my knee-butter.

I need to jump in the shower right quick before the knee-butter begins to solidify.

Knee push or knee button 

A visual artist or light architect, who hands are occupied pushing buttons, and he runs out of limbs to push with...he uses his knees to press the other buttons to go pew or kaboom. (Action)
