What is a flying jack?

A flying jack, often referred to as a "flying jacker," is a type of aerial maneuver commonly seen in extreme sports like Skateboarding or Snowboarding. It typically involves a jump where the rider extends their legs and spreads their arms, resembling the shape of a jack-in-the-box. The trick showcases both skill and style, often incorporating flips or spins for added difficulty. The term may also be used in other contexts, such as engineering or machinery, but it primarily relates to the acrobatic move in action sports.
