Anyone know the proper termanolgy for this move. Marcelo uses it alot from the x-guard. Ryan hall alls it the arm crush(er). Roy Dean calls it the telephon amlock. But most often I hear it reffered to as an inverted armbar. My teacher calls it an inverted armbar or Muso-Dori but that's because he spent 10 years doing Ninjutsu before he saw the light and that's what Ninjutsu guys call that armlock (Muso Dori). Anyone know the proper term??? Also, this may be tricker. What's the difference between inverted and reverse. Somebody told me inverted is when you/your oppnent is facing the opposite direction during the move; and that reverse is when the move is applied in the opposite direction. Is this inverted/reverse thing true, is it BS, or does it not really matter?
