Club good is a way of making sure that everyone in a group has an equal chance to take part in activities and share resources. It means that when a group of people come together, they talk about what they can share and do together, and then come to an agreement about how things will be shared fairly. For example, if a group of friends were playing a board game, club good would mean that each person takes a turn, and no one person gets to always play first or always win.
