Master Roshambollah!?

Check out rule 3:

RULE 3
The “Pump” consists of closing a fist and moving it in vertical fashion approximately 6”-10” in height, 3 times. This must be done in sync with the opposing player. Players may wish to chant “RO-SHAM-BO” to help them get in sync which is permissible.

...10", that's optimistic. And only 3 'pumps' before you 'shoot'. For shame!
