Chicken (game) is a game that involves two players and dares. One player has to do something or take a risk, and if they are too scared then they are the "chicken". It's a way of finding out who is the bravest. To play chicken, both players decide on a dare and then one player has to go first. They both have to do the dare. If one of them is too scared to go through with it, they are the "chicken" and they lose the game.
