Marty-McFly 

A trick in skateboarding. When you are done skating for the time being you and kick the tail of the board sending it into the air and lands in your grasp.

Explanation: Why are those kids so astoundingly happy when they received their (skate/hover)board back from Marty McFly in the Back to the Future trilogy? The only trick that he does is kick the board up to his hands and give it to the child... silly Marty, you ain't that sweet.

Ex 1: "Dude you've been skating all day... Marty-McFly that bitch and lets do something else"

Ex 2: "Yo, Marty-McFly your board and let me try a kickflip"
