This is a Half Truckhook Impossible caught in a 50/50. The rider stands on the Tail, puts their front foot under the board and starts to jump backwards, while also scooping the board in front of him. This will causing the board to flip over and get upside-down. The rider catches the Tail of the board with the front hand and lands with the foot which was under the board on the truck. There is also a no handed version of this trick which has not really a name. Commonly called "No-Handed Broken Fingers" by some freestylers. It's a crossfooted Half Truckhook Impossible caught into a No Handed 50/50. The reason why this trick got the name "Broken Fingers" is because how dangerous it can be. If you don't jump high enough and want to catch the board you are going to crush your own fingers.
