Conor McGregor Calls John Cena A 'Big, Fat 40-Year-Old Failed Mr. Olympia'

Less than a week after inciting the internet with comments that he could knock off the heads of most performers on the WWE roster, UFC fighter Conor McGregor spoke out against the current generation of wrestlers.

During a Q&A session promoting his UFC 202 main event against Nate Diaz, McGregor was asked about the backlash he received for his earlier comments -- particularly Ric Flair's comments which stated that McGregor stole Flair's gimmick.

While McGregor was respectful of Flair, he said the current generation of wrestlers -- much like he said in his tweet last week -- are not right in the head and called them "dweebs." He added that the McMahon family are "dons"

"The rest are dweebs," McGregor said (via Wrestling Inc). "What's the main guy? John Cena. He's 40, he's 40 years of age. He's walking around in a little miss orange t-shirt and a headband talking about [how] no one can see him. We can see him right there, he's a big fat 40-year-old failed Mr. Olympia motherf****r! They're dweebs, those guys!"

Cena is not known to be controversial and respond to criticism in a direct manner, he issued a tweet that seemed to an answer toward McGregor shortly after the Q&A made its rounds online

McGregor mentioned Flair's comments about there being wrestlers who could take McGregor in a legitimate fight.But McGregor said he's the "real s**t" and that if any WWE superstar wants to come his way, they are free to do so. He continued to show respect for the legends of the ring, but maintained his stance that the current generation of professional wrestlers are dweebs.

"Like I said, no disrespect to the Dons of the game," McGregor said. "I mean Vinny Mac's a f****ng legend. They wrote Vinny Mac [off] a couple of years ago, then he rose back up and he's back in the billionaires club. What he's been able to do with that bunch of dweebs he has over there at the moment has been phenomenal and I respect him for that. And then of course, the old G's of the game - The Rock, Stone Cold - they're all cool mother f****rs. Even Ric Flair's a cool motherf****r... but that new age of those guys are absolute dweebs... it ain't trash talk, it's true talk!"

Before McGregor made his latest comments, former WWE and TNA superstar Kurt Angle issued a challenge to the Irish mixed martial artist (via Sports Illustrated). He asked McGregor to undergo a remedial pro wrestling training session and to continue his critique of pro wrestling and its competitors then.

"I'd like to challenge Conor. Take five bumps with me in the ring. Just five bumps. When I did that for the first time, I took three and said, 'F— this, I'm quitting.' I quit for a couple days and my manager talked me into going back. I know how Dana White and Conor continue to bash the business, but I challenge either of them to get in the ring with me and take five bumps. Once they do, they'll realize how tough it is–and that's not even a fraction of what it takes to be a pro wrestler"
