Wedgie (also known as Bomb Drop)
Thanks very much to Bonnie Curtis, who taught me this game when I visited her Pathfinder meeting!
You will need a largeish coin ("loonies" or "twoonies" work well) and a paper target for each team. Divide your group into teams and have them line up at one end of your playing area. Place a paper bull's-eye target or other receptacle at the other end of the playing area. At "go", the first girl in each line takes the coin, wedges it between her bum cheeks, and shuffles as fast as she can to the target! When she arrives, she has to drop the coin onto the target, aiming for the centre! You can have someone to keep score if you like. This game is a hoot!
