A term used in target archery when an archer shoots an arrow close to a scoring line and proceeds to call it in the higher scoring area when the rest of the shooting party identify the arrow as clearly being in the lower scoring area. The archer will then typically continue to protest for weeks or even months calling the arrow in and proclaiming the higher score.
