Skateboard trick invented in the late 70’s by David Andrecht. Its always been a barometer of how well I am skating or how good my back is holding out!. Back in the old days I loved this trick and I could huck them up at will. In recent years they have been on and off, I have never been able to flap them over like the Jason Jessee picture. The most recent pic looks like I am leaping out or letting go too early, what a total spazz!
