That's Not A Hoverboard

Why is everyone calling those two-wheel things "hoverboards?"

Roll. No hover. We're just calling shit whatever now? Then I didn't get a Mazda 3 Zipcar and go to Target to find a new trash can. I got a spacebuggy and went to Narnia to find a Horcrux.

You can't just say stuff is other stuff when it clearly isn't.
