The feud between UFC champion Conor McGregor and WWE continued yesterday during a media day to promote UFC 202 next week.

Last week McGregor said he would slap the heads off of all the WWE locker room guys and called the Superstars “pussies” in a post on Twitter. Several shot back, including Ric Flair, Chris Jericho, Big E, Roman Reigns, Sasha Banks, and others but perhaps McGregor’s worst comment came in yesterday and was directed towards John Cena.

“He’s 40. He’s 40 years of age. He’s walking around in a luminous orange t-shirt and a headband talking about nobody can see him. We can see him right there. He’s a big fat, 40-year-old failed Mr. Olympia motherf*cker,” McGregor said.

Responding to Ric Flair, who he said he made a living stealing his gimmick, McGregor said, “This ain’t no gimmick. This is the real sh*t. I’ve gotta get in and fight a man for real. With no script, with no nothing,” he explained. “He was talking about bringing some other wrestler guys out to challenge me. Come bring it. If they want to do that, come at me and see what happens.”

McGregor admitted that Vince is a “f*cking legend” and respects what he has been able to do with “that bunch of dweebs he has over there at the moment.” He also praised The Rock and Stone Cold Steve Austin and described them as “cool motherf*ckers,” and even though Ric Flair dissed him back, he said he’s cool as well.

“When I listen to them talk, when I listen to them carry themselves, they just don”t seem right in the head. That might have been a bit rudeness for me to say, but again: It ain’t trash talk, it’s truth talk,” he concluded.
