Leonardo DiCaprio -- Kick-Ass Times On a Yacht

Leonardo DiCaprio was kung fu fightin' the hell out of someone in his mind ... as he ripped off some seriously high kicks in the South of France.

The Wolf of Wall Street was kicking air, taking names, and rocking a pony ... while onboard a yacht off St. Tropez Tuesday. 

We know Leo loves MMA ... so the kickfest could be a new workout regimen -- or maybe he seriously wants a rematch with the guy who crushed him at Coachella.
