"Listen, there's three unions out there now all battling against each other and if you're a fighter, these guys are all looking to get in your pocket.
"It's a business where guys are going to make money and as a fighter if this is what you want to do, you've got to figure out who's hand you want in your pocket and I guarantee you don't want Bjork's hand in your pocket."
During the two-hour long conference call that introduced the MMAAA, Rebney took aim at the UFC by claiming that the promotion pays athletes only eight per cent of the total revenue earned by the company and he wanted to increase that share to a 50 per cent split.
White scoffed at Rebney's numbers and also blasted the former promoter after he said that his most successful year in mixed martial arts was when he paid athletes 53-percent of his revenue.
"The one thing that I do know that came out of this thing, is that this scumbag - who knows nothing about our business - he says, 'Yeah, they only pay the fighters eight percent of the revenue.' I hope you're talking about Conor McGregor. Okay? We're paying eight percent of the revenue, you must mean Conor McGregor, right Bjork, you stupid motherf***er," White said.
"He's saying, 'When I was a promoter, I paid 53 per cent of the revenue (to the fighters)'. Cause there was no f***ing revenue. Yeah you're paying 53 per cent - there was no revenue! If that's the way we're going to gauge this back in the old days, then I was paying 250-percent of the f***ing revenue. What a f***ing piece of s*** this guy is, oh my God."
White went onto say that the only reason Rebney was involved with the MMAAA is because he was "unemployed" while also warning the fighters working with him to be aware of who they're in business with now.
"Listen if you're going to have a guy in your pocket and you're a fighter, you might want to go out and ask some other fighters what they're opinion is of this f***ing scumbag," White said, adding that Rebney's motive was that "he doesn't have a job".
As far as the fighters go, White says he doesn't have an issue with anyone being involved with the MMAAA regardless of what was said on the conference call that introduced the group.
Out of the five competitors who were introduced with the MMAAA, the only one White was seemingly irritated about was Donald "Cowboy" Cerrone.
"Not at all. At the end the day, here's the reality - the fighters can go out and do whatever they want to do. They're all grown men and in life we all have these paths to walk down," White said.
"I'm a little shocked, I'll tell you this, that 'Cowboy' Cerrone didn't give me a call. If you're that unhappy..."
Cerrone was one of the five fighters leading the charge during the introduction of the MMAAA. White pointed out a legal issue he helped sort out for Cerrone as proof that he's been there whenever he needed it, but this time around the former title contender didn't bother to call the UFC president to explain what was happening.
"First of all he's only main evented like three fights, never held a title in the WEC, never held a title in the UFC, and a couple years ago he was on his boat, he gets into a beef with a guy on another boat. He's in big trouble. Who does he call? He calls me," White said.
"What do I do? I go out and find him the best criminal defense lawyer and I spent over $100,000 of my own money, for "Cowboy" Cerrone. When I see 'Cowboy' standing up there it's like, 'All right, really? OK'.
"Never heard a word from 'Cowboy' but whatever. It's all good. I never called him. Never called any of the guys. He's a big boy, he can do what he wants to do."
