Gomu Gomu no Wave. Pretty simple, Luffy grabs an opponent with both hands and then starts shaking them by making waves travel up his arms to the person (think about when you flick a rope, that kind of wave, only on Luffy's arms). It jostles them around a bit, great for torture or if you need to shake something out of a jar.
