In the sport of soccer, the term "offside" is commonly used. A player is deemed offside if they are positioned closer to the opponent's goal line than both the ball and the second-to-last defender when the ball is passed to them, unless they are in their own half of the field. This rule ensures that attacking players do not gain an unfair advantage, promoting fair play and strategy within the game. The offside rule can be a source of controversy and debate, often leading to significant moments during matches as players strive to avoid being penalized.
