The rule is a game, were you have to make an OK sign with your hands below the waist; If someone sees it then you can do one punch to them. If the person who sees it puts their finger in the hand and gets it out without being caught, they get to punch you 5 times.
billy used the finger rule on his friend, but his friend quickly put his finger inside. Billy got punched five times.
