Get the Jackhammermug. 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.
