I don't know, I've never heard of anything as crazy as the talk in this thread.

You move your wrist/maybe arm up and down verticly, keeping your hand verticle for the "rocks" "paper" "scissors" "shoot!", turning it sideways if you throw out paper is extremley innefficient. Also, in my league we moved away from saying "Rocks..." outloud, to a more silent, professional approach, that allows for greater concentration.
