Outside-In

From Ultipedia

Outside-In or OI describes a disc's flight path when the path curves with the discs rotation. For a right-handed player, an OI forehand moved right-to-left and an OI backhand moves left-to-right. In disc golf, this throw is called an "anhyzer" or "annie".
In Ultimate, an OI throw is used to curve a thrown disc around a defender.
