The Game of Beer Golf
Beer golf is a very unusual drinking game. It involves setting up eighteen cups around your house in random rooms and locations and eventually playing against other people who want to get the ball into the random cups - just as you would at a golf course. Before the game begins you set up the random cups all over an everyone has to agree on the locations. A lot of these locations have to trick shots involvedand should be a medium to hard difficulty.
Once all the cups are setup the players each take turns shooting at the first cup in the rotation. Depending on how good you are you won't take multiple strokes or a.k.a. shots at each cup. The player with the lowest score for that hole would win that hole. At at the end of the first nine holes you tally up how many strokes it took you and do the same at the end of the last nine holes. you can add variance to this by making the other player drink for every hole he loses as you go. Although that is not for the light of heart, this is a really fun game though especially when you incorporate many trick shots such as bouncing off walls, down stairwells etc..
Bonus note: dressing up in golf gear always adds extra flavor to the drinking fun.
