Offside

when an offensive player is in the oppositions half of the field, the or she has to have at least two oppositions players between him and his opponents goal line at the moment the ball was passed to him. Offside and an offside position are not the same; being in an offside position is allowed as long as the player does not have anything to do with the game play, offside on the other hand is defined as being in an offside position, while involved with the game play.
