Sounds like the game my dad and uncle have been playing for the last 20 years. They've been stealing a little stone alligator from each other everytime they get the chance.
Spunds similar to a family game of mine, excapt with beers. Someone bought "Beer" brand beer from a military PX and has been passing it around at parties. I have wisely avoided it thus far but fear I will one day be drunk enough to drink one. I've heard the generics are the worst.
