THE DISRESPECT IS REAL!!!!
Khabib Nurmagomedov straight up KICKED Tony Ferguson's interim UFC lightweight championship belt during an intense face-off Friday ... and it got VERY close to getting violent.
Khabib and Tony were doing a media event to promote their upcoming brawl at UFC 249 in April ... and the trash talk got VERY personal.
Tony trashed Khabib as a weak-minded, scared, fake brawler ... and Khabin fired back by calling Tony a "fake Mexican," since Tony was born and raised in California.
Tony was offended by the comments -- claiming he's a proud American AND a proud Mexican.
