Off-Angle:

An off-angle is a position held from an unusual or unexpected angle so an opponent’s crosshair placement does not line up with it naturally. In Counter-Strike 2, players use off-angles to make peeks harder to clear and to gain an advantage in a duel. They are common on defense, where changing the look of a standard position can force a late reaction or a missed pre-aim.
