Storrs 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?"
"Me and Paul gave her the Storrs Jackhammer!"

Callahan Jackhammer

After a male and female have rough sexual intercourse, and the female's leg starts shaking and vibrating, thus not being able to walk.

Dude, I just gave her the Callahan Jackhammer and she won't be able to walk for a bit!

Ballard Jackhammer

A sex act wherein a male intermittently thrusts quickly and loudly for 5-30 second intervals, alternating with minutes of complete stillness and silence. Said male begins while his partner is still asleep and continues for several hours.

Some f*#%face woke me up with the Ballard Jackhammer again this morning. It goes on all day and leaves me unsatisfied and agitated.
