Bad egg is a children's playground ball game played in Great Britain and other countries.One player is chosen as the 'Bad Egg' and turns their back to the other players. 'Bad Egg' then asks the others to each name something from a particular group (for example, each player is to name a colour, or a sports team, etc.). Once each player has answered, the 'Bad Egg' throws a tennis ball over their shoulder, and shouts out one of the answers that had been given by the other players.
