1. A sexual manuver of constant re-penetration; basically taking the dick in an out of the vagina (or anus) repeatedly, in a 'jackhammer'-like motion / or jacking off on a chick's face from a really short distance away
2. a prototype 'automatic' shotgun (worked with a feeding mechanism much like a revolver), was designed by John Andersen, it fires 12 gauge rounds, in a 10 shot 'magazine', has a ROF of approximately 4 shots per second. These are not really in any form of production

sex position that is as follows...
the girl is lying off the bed with her shoulders/neck on the ground and torso against the bed, she is required to hold her legs back as far and wide as possible so we can begin. You start by bending ur boner down so that you are able to stand with your legs wide and thrust in a downward motion into her pussy (like a jackhammer). you then increase speed and many will at this point adopt the superman stance. meaning you place a chair 1 to 2 feet beyond her head on the ground and grab the sides so you are parallel to the floor and are able to use your hip thrusters to pound away at the pussy. this develops great lats and abs, while also feeling great on ur downstairs. The Jack hammer
