Start with a ball or a rolled up sock or bandana. One person (the flinch master) stands in the middle of a circle created by everyone else (group size is n/a). The people making up the circle should stand about 8-10 feet away from the flinch master. The flinch master tosses the ball, or sock or whatever to each person in the circle in no particular order. This is an elimination game, in order to get the people out the flinch master tries to get them to flinch by pump-faking a throw. The people in the circle stand with their arms crossed over their chest and are eliminated if they flinch when the ball is not thrown to them or if they drop the ball. The ball must be thrown underhand and people playing will determine if a dropped pass is a good throw or not. The last person standing becomes the new flinch master.
Non-competitive version: Make two games happen simultaneously. When one person is ÛÏoutÛ in one circle they move to another. After a designated time, the flinch master is replaced.
