ENOUGH WITH THE FRICKIN' HOVERBOARDS ... so says Tony Hawk.
The skateboarding legend has several gripes with the 2-wheeled scooters ...
First, they look ridiculous.
Second, they're NOT REAL HOVERBOARDS.
Tony would know ... he actually test drove a REAL hoverboard at a special skate park last year.
Check out the clip ... Tony says he can't support the trend -- and wouldn't be upset if they were BANNED altogether.
Marty McFly would be proud.
