Dana White, the outspoken mogul behind Ultimate Fighting Championship (UFC), launched another Twitter firestorm today by insisting there is no such thing as professional wrestling.

“Never heard of it,” White tweeted after a fan asked for his thoughts on World Wrestling Entertainment (WWE).

“Frankly, it sounds made-up.”

White’s latest accusations about the nonexistence of wrestling come on the heels of earlier remarks in which he described wrestling — the biggest form of competition for his mixed martial arts promotion — as “fake sh*t.”

Now White has taken his dismissal of WWE even further, refusing to acknowledge there is such a company: “Is that the World Wildlife Enterprise or something?”

White even refused to acknowledge the existence of former UFC champion and current WWE headliner Brock Lesnar, insisting that Lesnar’s name “doesn’t ring a bell.”

Asked whether he has emulated wrestling impresario Vince McMahon, and co-opted all of McMahon’s showbiz razzle-dazzle to popularize UFC, White merely replied: “Who?”

Many pundits believe White is being especially belligerent on the subject because he doesn’t want the toughest fighter in UFC, Ronda Rousey, to move to WWE and get pummelled mercilessly by Stephanie McMahon’s killer breasts.
