Shaun White
Shaun White is one of the most famous snowboarders in the world, and that's not just because of his talent. White has been accused of acting rude and entitled, having shut down entire snowboarding parks to be the only one there. A particularly nasty story about White is when he ditched sick kids from the Make-A-Wish Foundation that wanted to snowboard with him. Not only did he bail on the children, but he did it specifically to ride the half-pipe alone!
