In an effort to set up the biggest boxing bout of his entire life, infamous YouTuber Jake Paul unleashed an expletive-filled call out directed at UFC megastar Conor McGregor. The 23-year-old online sensation once again grabbed headlines for all the wrong reasons with this cringe-worthy attempt for a promo on Monday.

Paul, who is coming off that sensational two-round knockout of retired NBA player Nate Robinson earlier this month, brought out the big guns in an effort to goad the Irish superstar into a potentially huge payday. The younger brother of Logan Paul did his best McGregor impersonation, as he was seen draped in an Irish flag while smoking a cigar and drinking whiskey in the now-viral clip.

Jake Paul, meanwhile, certainly understands that he has to sell a fight of this magnitude before turning it into reality. He hurled several NSFW insults McGregor’s way and even crossed the line a bit when he talked about the former two-division MMA champion’s wife and his recent run-ins with the law. He even tried something on social media, following nobody else but Conor’s wife on Instagram.

Then again, Conor is known for his own shenanigans back in the day when he was just making a name for himself in the UFC, so it’s clear that Paul was taking notes.

Paul also set his sights on UFC President Dana White, calling him an “ugly, bald b**ch”. Earlier, White claimed that McGregor vs Paul fight has no chance of happening under his watch.

McGregor’s last foray in the boxing ring was way back in 2017, where he endured a TKO loss to Floyd Mayweather Jr. He also returned to the UFC cage last January, knocking out Donald “Cowboy” Cerrone in one round. Paul, meanwhile, has gained some notoriety in recent years after shifting to professional boxing. He is undefeated in two fights against a rapper and a former basketball player.

It remains to be seen if McGregor will address Paul’s disrespectful challenge. Paul is clearly biting off more than he can chew on this one.
