A seemingly innocuous Bellator 141 poster signing got heated when Patricio Freire and Georgi Karakhanyan, who have been bickering virtually on social media, finally met up in the real world.

Coach Eric Albarracin posted the above video (via Facebook) of the confrontation (warning: there’s some foul language, including an abundance of f-bombs).

Bellator 141 takes place Friday at Pechanga Resort & Casino in Temecula, Calif. In the Spike TV-televised co-headliner, Karakhanyan’s training partner, Saad Awad (18-6 MMA, 6-2 BMMA), takes on Patricio Freire’s brother, Patricky Freire (13-6 MMA, 6-5 BMMA).

However, when the camps arrived to the customary pre-event poster signing, tempers boiled with featherweight champion Patricio Freire (24-2 MMA, 12-2 BMMA), who defeated Karakhanyan (24-4-1 MMA, 3-2 BMMA) in 2011 and saw their planned April rematch scrapped when the challenger suffered a torn ACL. Karakhanyan eventually wants another shot, but first up for “Pitbull” is a title fight with Daniel Straus (24-6 MMA, 10-3 BMMA) on Nov. 6.

Here’s a summary from Albarracin:
