When a man it is getting a massage and tucks his dick down between his legs. His partner while massaging his butthole begins to jerk him off, right as he is about cum his partner starts jerking his dick so hard that it hammers your nuts and blows your load on the wall where there is a target.

When a random person (usually a hobo or homeless person) goes up to any male walking down the street at random, and out of nowhere, quickly pulls down their pants and jacks them off at the speed of a jackhammer as they immediately ejaculate with no warning. The person doing the act then sprints off. The entire process is completed within a matter of seconds. This often occurs in Casper Wyoming which is in Natrona County.
Jake received the Natrona Jackhammer and didn’t catch a glimpse of the culprit!
Woah! I just got Natrona Jackhammered!
My friends and I are going to Natrona Jackhammer some people.

When a man spreads the woman's vagina flaps and attempts to stick his head into it. This normally ends up with a trip to the ER as it is not safe for both genders. This can be done with the same sex (see Finnish jackhammer).

A sexual position. Similar to the pile driver. One standing partner holds another partner, by the hips, while second partner is standing on their head, legs spread in a T shape. Standing partner is generally a male since insertion of the sexual organ is a prerequisite for completing the position, but First partner may be a female wearing a strap-on. (though this may evolve to its own new position) -----First partner, with firm grip on second partners hips, and with sexual organ (or facsimile) fully inserted, (orifice of insertion depends upon sex of second partner, as either sex is possible, though a women presents more possibilities) pretends that second partner is a jackhammer (making Jackhammer noises is not required, but is suggested for authenticity) and lifts second partner, then drops, lifts, then drops, repeating this process until orgasm or boredom sets in. FOR FULL EFFECT first partner should occasionally blow hard onto the partner and smack them with snowballs to simulate the driving wind and snow of the Connecticut college town.
"Hey what did you do with that girl at Towers last night?"
