In this piledriver a wrestler will bend his / her opponent forward, placing the opponent's head between the wrestler's legs (a standing head scissors), and hooks each of the opponent's arms behind the opponent's back. He / she then pulls back on the opponent's arms lifting him/her up so that the opponent is held upside down facing in the same direction as the wrestler, the wrestler then drops to a sitting or kneeling position dropping the opponent's head into the mat.
The version which sees the attacking wrestler fall to a seated position was popular with several wrestlers based around independent promotions on the west coast of the United States, where it is known as the Tiger Driver '98.
There's also a variation known as double chickenwing piledriver, where the wrestler just put his/her opponent into a double chickenwing instead of a double underhook.
