The Stiffy is a type of air tweak. This trick is usually done on frontside airs or straight airs. Skaters do a normal air while grabbing the toe side of the board with their back hand. At the peak of their air, the skaters legs are straight in front of them like a Pike in gymnastics. This trick looks like a jackknife off of the diving board with no water in the pool. The straighter the legs and longer the tweak, the cooler this trick looks.
