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

Jacking off into your hand and then slapping your buddy with your cum and then slapping them with flour.

Created after the orginal thought of the drill, the jackhammer takes speed and power in order to work. Start by creating a fist. Then, get into a stance that will allow maximum power and speed. Arch your back forward and thrust your fist through your other hand, in some what of a punching motion. Try to build up speed. That is the secret of the Jackhammer. Kids, don't try this with grandma in the room.
"Your Drill's got nothing on my Jackhammer"
"Why don't we just stick the Jackhammer in with all the other tool techniques."
"I hope you're proud. Damn you drill and Jackhammer!"

A particular method of thrusting used only by advanced sex fiends or clueless morons. Commonly utilized when yo bitch is in teh Deep Thrust position.
The Penis is inserted into the vagine, and the body is moved forward until the penis enter the vagina at a 90 degree angle. A lot of the pleasure in this posisition is derived, I believe, from the fact that the vagina isn't in a perfectly upwards (90 degree angle) which leads to some awesome griding acckkkshunn :DDDDDD~~~~
