piledriver is a professional wrestling driver move in which the wrestler grabs his opponent, turns him upside-down, and drops into a sitting or kneeling position, driving the opponent head-first into the mat. The most common piledrivers are the basic belly-to-back, or Texas piledriver, and the belly-to-belly tombstone piledriver, but many more intricate variants are in use. It was innovated by "Wild" Bill Longson.
The name is taken from a piece of construction equipment, also called a pile driver,
that drives countless massive impacts on the top of a large major
foundation support, burying it in the ground slowly with each impact.
The act of performing a piledriver is called "piledriving."
Someone who has recently been the victim of a piledriver is said to have
been "piledriven" (e.g. "The wrestler was piledriven into the canvas").
