This only works in versus with Cin Drallig. first grab the opponent. Second, immedeatly press x x y. Then repeat. if done right the opponent cant get a single hit on you once you grab him the first time. Oh, and if you are grabbed press x and y at the same time repeatedly.you may get out. if your facing General Grievous and he gets the head lock and shoulder break on you and then throws you onto the ground to step on you then keep pressing x and y repeatedly and you should roll away.
