bump-stick

A piece of wood shaped like the stock of a rifle, with a horizontal bar projecting from one side. It magically turns semi-automatic weapons (those which fire one bullet per pull of the trigger) into bullet-hoses; a device which uses the recoil of a gun to fire the next round.
One of many ways to turn your shitty california-legal semi-automatic AR-15 into a machine-gun. Very popular in US states where semi-automatic rifles are legal; chiefly used by man-children and 13-year-old boys. On the down-side, it seriously impedes accuracy, and thus is useless for criminals.

Imma take my SKS and bump-stick and shoot some dirt!
Just plug in your bump-stick to turn your glock into a matrix-style machine-pistol!
I used a bump-stick and hit nothing but air.

A dance with someone you would fuck, or with whom you would otherwise enjoy pubic area contact while dancing.

I would never bump-hump my mom or dad. Any pubic area contact while dancing with either one would gross me out.
