Ultimate Fighting Championship (UFC) superstar Conor McGregor was inside 1 Oak Nightclub last Tuesday night (Nov. 15, 2016) in New York City, bragging about his recent title win at UFC 205 while burying Floyd Mayweather.

Hey, when you pull this off, you’ve earned the right to brag.

Former Strikeforce welterweight champion Nick Diaz, who was inside the nightclub for reasons that are of little importance to a story like this, was thoroughly unimpressed with the “Notorious” accomplishment achieved inside Madison Square Garden.

“I was already a two-weight world champion, bitch,” Diaz told his Snapchat followers.

McGregor has a history with the Diaz clan after splitting a pair of fights against Nate at UFC 196 (loss) and UFC 202 (win). There is already talk of a potential rubber match somewhere down the road, but I’m sure no one in the combat sports industry would complain if the Irishman moved back up to 170 for the elder Diaz.

Just don’t tell this guy.
