The "tool"-ful art of stacking \ collecting 3 or more plastic "dixie" cups (the more the better) after finishing the consumption of the alcholic contents. This is to show off that you are more macho than the rest of the crowd/men. Usally seen at large social gatherings \ events. (ie $1 beer night @ the baseball game)
Hey dude don't be a tool.. get rid of your macho cups!
