The Misty Flip is a backwards-flipping frontside spin performed on a straight jump with a snowboard. Similar in rotation to a McTwist, this maneuver is typically performed as a 540° rotation.
In order to perform a Misty Flip, a snowboarder throws his back shoulder (and arm) to his front foot, commencing a frontside spin while his head and body 'backflip' toward the nose of the snowboard. This motion initiates a rotation that mimics that of a McTwist, which is generally performed in halfpipes and on quarterpipes. However, because the Misty Flip is performed on a straight jump, it is further distinguished from a McTwist because the snowboarder lands backwards following the 540 rotation.
The Misty Flip was first popularized by Peter Line in the video Transworld Snowboarding Video Magazine Volume 1.
