To skate so hard you’re coasting by.

A super rad board that hovers above the ground. Like a hovering skateboard! Most notably seen in Back to the Future 2, the hoverboard has become more than a myth than anything at this point. However with new scientific advancements it seems more and more likely that maybe someday we will get a hoverboard.

A self-balancing scooter that is typically used by douche bags, viners or both. The scooters are most commonly called "hoverboards" but they also go by names such as Glidrs, Swegways, or IO Hawk boards due to the leading brand that sells the boards named IO Hawk. The boards are called "hoverboards" contradicting the fact that the boards have wheels and don't hover much at all. They are expensive, ranging from $200-$700 so rich white kids who want to live in the future can ride them around once a month.

A piece of shit that can't hover but can only stay on two wheels and blow up

a NON-floating board, just like a segway, but without the steering wheel.
