"Chuck" refers to the action of tossing or throwing something with a quick motion. It often implies a casual or informal way of throwing, rather than a precise or forceful action. People might chuck a ball, a piece of paper, or even small objects like a rock during play or while cleaning up. In sports, such as football or baseball, players may chuck the ball to teammates or during practice drills. The term can also be used in everyday situations, like when someone chucks their keys onto a table or chucks a snack into a bag for later.
