The Pedigree is professional wrestler HHH's finishing move. The technical name for this move is a double underhook DDT.

Executing the Pedigree is simple. HHH sticks his opponent's head inbetween his legs and then lifts both of his opponent's arms up past their head. He then jumps slightly, landing on his knees and driving his opponent face first into the canvas.

This is actually a slightly dangerous move, as if the opponent's head was too low at the start of the maneuver, there's a chance he could actually land head-first and injure his neck.
