Kai Lenny is a professional big wave surfer living in Hawaii and he decided during a recent surf swell that he would amp up the big wave surfing thing a little more. How you amplify something like big wave surfing that is already super dangerous? How about you throw in some flips, while you're riding down massive waves in Hawaii? This is some amazing video from drones, from PWC in the water and more showing Kai throwing flips while riding these giant waves. The best part is that he leaves in some of the times that it definitely did NOT go well for him. We are just amazed this guy can surf with such giant balls! Check it out:
