Jon Jones gave Snoop Dogg a private backstage MMA lesson in Albuquerque Tuesday night -- complete with a spinning back elbow tutorial ... and the whole thing was caught on video.
Snoop invited the UFC star to his dressing room before his show with Wiz Khalifa -- where they all did a little friendly slap fighting ... and Jones broke out a spinning elbow.
Snoop LOVED IT -- and demanded Jones teach him how to throw it himself. Jon complied.
Don't expect Snoop in the Octagon anytime soon ... you know ... drug tests and such.
