A game usually played at recess in which you use any type of circular ball and play a type version of keep away. The teams keep the ball away from the other and can be given up by tackling the one with the ball, or result in extreme violence. This is where Robbie comes in. During intensive play action, any man named Robbie has to get in the middle of the action and try to stop it (if you don't have anyone named robbie, assign one) and will end up getting hurt. Whoever gets the claim for hurting Robbie and making him complain, angry, or even cry wins the round and a point for their team.
We were playing Robbie ball after lunch and our team lost in seconds, our best player Dom, hit him in the nose and Robbie flipped so Tyler's team won.
