Jason Momoa Says He's a 'F***ing Amazing' Snowboarder!!!

Jason Momoa not only owns the land beneath the sea ... he owns the ski slopes too!

We got the coolest man at the Sundance Film Festival Friday night leaving Butcher's Chop House in Park City, Utah, and he declared his impending dominance on the slopes. Jason says he's breakin' out the snowboard Saturday and he will be king of the mountain.

He's certainly king of the sea. "Aquaman" has become the highest grossing DC superhero flick, grossing more than a billion bucks.

Jason's at Sundance to host a panel on, "The Creatives Behind Some of YouTube's Buzziest Channels."
