Conor McGregor brutally trolled Jake Paul after Amanda Serrano, who the YouTuber turned boxer promotes, lost to Katie Taylor.
Moments after the fight, the Dubliner, who has had many previous back-and-forths with Paul, took to Twitter to take aim at the American.
McGregor wrote: "Who the f*** is this jackass in the pink Jimmy Saville glasses?"
Paul later responded by saying: "I'm the one who has done more for fighters than you ever have; the one who has won five fights in the past two years while you have lost five. The one who isn’t owned by Dana White, the one who made the fight you just watched happen, the one who got your hero Katie Taylor paid, that’s who."
McGregor then posted a picture of Saville wearing similar pink glasses to Paul.
McGregor also congratulated Taylor on her victory, adding: "Katie Taylor The Greatest! Absolutely incredible boxing! Take a bow ladies! What a contest!"
But Paul vowed to settle his problems with McGregor "some day" at the post-fight press conference.
He said: "It is what it is. Of course Conor's watching to support Katie.
"We had a little bit of banter back-and-forth, but of course he always has something to say but he doesn't really have a place to talk. He hasn't won a fight in five years, Dana [White, UFC president] owns him and I'm the one that got Katie Taylor a big payday and that's his hero.
"Conor McGregor's not tall enough to ride a rollercoaster and I feel bad for him because he's ducking me. But we'll get that settled one day."
