Pizza Flip
From Ultipedia
Useful in faking a short throw, execute the Pizza Flip by starting a standard forehand throw; but at the last moment rotate the disc counter-clockwise (for right handed players), under the throwing arm, using only the middle finger and the momentum of the spin to hold the disc. The Pizza Flip is then released towards the dominant side of the thrower, perpendicular to the direction of the standard forehand throw.
