Apparently this all started because of Mitrione's comments about Jenna Jameson and Tito himself.
Here's what Meathead orignally said.
“I think it’s awesome…AWESOME that the UFC is finally doing this. I think that it’s a great promotion that they’re finally letting women fight for their man’s honor. I think that’s a great thing. We all know that Tito’s gonna give some type of excuse and back out, so Jenna’s gonna have to step in and fight Bader for Tito’s honor,” Mitrione deadpanned. “Bader, be really careful because it’s a trap fight. We all know that she’s awesome off her back and she’s got phenomenal top control, but remember that she doesn’t choke easily.”
Their Argument in the video went something like this according to Cagepotato.
Tito confronted Mitrione and “Meathead” told him it was only a joke and he was sorry if it offended him. When Tito refused to accept his apology, Mitrione was ready to throw down.
“Well then I guess we’re about to scrap then. I’m not the one who’s getting aggressive. You’re the one that’s getting aggressive. Hey, I apologize if I hurt your feelings. I apologize if I hurt your feelings,” Mitrione offered. “Yeah, well, **** you then. You’re the one ******* your boss and you’re the one that wants to scrap. Aren’t you the one who wants to scrap?”
Oddly enough Jenna actually commented on Meatheads remarks and said they were hilarious.
