A group of four highly trained athletes, rumoured to be ex-special forces, that compete in extreme adventure races whilst praising the virtues of regularmasterbation
"You have a date last night?" "No, I was a masterbeater"
" Man! You gotta train good to beat those masterbeaters!"
An internet multiplayer gamer obsessed with individual performance in group based activities to the exclusion of the overall objective. A player who is so consumed with individual performance excellence in groups, they appear to receive sexual gratification from it.
I am more interested in helping the raid be successful than being a meterbeater.
