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 kick second partner in the ear to facilitate the ear ringing brought on by the close association with a Jackhammer on the confines of a packed Brooklyn street.
-----Warning: position, if attempted should be executed on a mattress or other soft or padded surface since the risk of concussion and or neck injury is considerable, execution on the floor or any other hard surface is inadvisable. actual execution of this position period is inadvisable.

The act of receiving a blow job while your partner is laying upside down on a couch (with feet in the air) . . . with the receiver leaning over the giver ....in this position the giver is staring at the gouch (hairy region of the body between your asshole and ball sack) of the receiver . . thus the jackhammer (your monster cock) comes in when the giver is pounding the back of the receivers throat....while pounding away the giver farts on the face of the receiver.
i was wearing high heels while receiving a windy jackhammer and thats when he accidentally shit on my face instead of just farting.
