its a move that usually only works in kids wrestling. good kids in high school usually don't get put into that move. I used to think it was a cool move and would try it. I think the ref will stop the match if you pull the legs apart straight out and the kid yells. if its taken at an angle and the kid doesn't yell out loud then the ref wont stop it. I probably wouldn't show my high school kid the move though. many other moves that have a higher percentage of actually scoring points off of it.
