When numerous persons with the name of Jack gather and compete over who can pleasure themselves the best, most efficiently, or fastest. Any other competition parameter works under this term, but it must pertain to multiple Jacks masturbating.
"Hey homie, did you attend the Jack jack off off last night?"
"Yeah man! Jack was on fire, but other Jack finished in record time. I couldn't believe my eyes!"
