Conor McGregor attacked Khabib Nurmagomedov on social media after The Eagle's win against Edson Barbosa.Commenting on Khabib and Barbosa's performances, McGregor tweeted: "That Dagestani was dog sh*t the other night you's are all nuts. Game full of sloppy bums asking to be slept. Pay me my worth and Kings back."That Dagestani was dog shit the other night you's are all nuts. Game full of sloppy bums asking to be slept.

McGregor took another shot at the Dagestani fighter in a reply on social media. He said, "I slaughter your pets and wear them as coats. And I only wear them once."You can buy them on Gucci storeBut in the octagon bear will eat you.#McTapper #🐻vs🐓 pic.twitter.com/O2Qo0HhZab— khabib nurmagomedov (@TeamKhabib) January 2, 2018Khabib gave the Irishman a witty reply, saying, "You can buy them on Gucci store; But in the octagon bear will eat you."

With The Eagle gone, hopes for continued episodes of rivalry between him and Conor McGregor also washed away.Conor McGregor even bid The Eagle a respectful farewell on social media, saying he would "carry on" without him. However, the deeply-embedded notoriety in Conor McGregor never really let him carry on.On March 21, 2021, in his response to another retirement confirmation, Conor McGregor took a shot at Khabib Nurmagomedov on social media, reminding the Dagestani about his career inefficiencies. Calling Khabib a "teddy bear", Conor wrote: "8 ko/tko across 30 fights = zero power. Don't forget it teddy bear."8 ko/tko across 30 fights = zero power. Don’t forget it teddy bear.— Conor McGregor (@TheNotoriousMMA) March 21, 2021Another instance of Conor McGregor's social media offensives came just a few weeks later, again targeted at the retired Khabib Nurmagomedov. Conor recalled the incident from April 2018 when he had thrown a steel dolly at the UFC 223 bus carrying Khabib and other fighters from the event.Although penalized for the offense, Conor McGregor said after the bus incident that Khabib Nurmagomedov hadn't come out of the bus as he was scared. This claim was contested by Khabib during the UFC 223 press conference.The Notorious also referred to one of Khabib's tweets from 2014 where The Eagle had asked for a custom McGregor t-shirt. In an attempt to irk Khabib in his retirement, Conor McGregor tweeted: "Get this man a t shirt! And a nappy for the bus."Conor McGregor deleted the tweet minutes after posting it#1 - Conor McGregor vs Dustin PoirierDustin Poirier and Conor McGregor touch gloves at UFC 257When Conor McGregor went for the rematch against Dustin Poirier at UFC 257, a lot of people, including Poirier, felt that The Notorious had died. In his place was a well-behaved man who engaged in niceties.A few months after the fight, however, Conor McGregor corrected his image. With the McGregor vs Poirier trilogy in talks, McGregor returned to his old 'Mystic Mac' self, predicting fight outcomes.The 32-year-old posted on his Instagram that he would defeat Poirier in round four. Conor wrote: "The prediction is in! I’m going to win the trilogy fight via A Front Kick to the nose. Round number 4. His Nose needs straightenin and I’m Rhinoplasty". View this post on Instagram A post shared by Conor McGregor Official (@thenotoriousmma)Dustin Poirier replied to Conor McGregor's social media offensive and claimed that just like the Irishman's prediction of making a donation to Poirier's foundation, his fight prediction would fail too.While Conor McGregor explained why he did not make the donation, he also went on to insult Dustin Poirier, marking the complete revival of The Notorious.A donation, not a debt. We’ve been awaiting the plans for the money that never came. I do with all my donations. Know where it’s going dot for dot. Otherwise it goes walking. As is the case with a lot of these foundations, sadly. You took the McG over the belt shows I was right.— Conor McGregor (@TheNotoriousMMA) April 12, 2021My team does their due diligence to make sure every donation meets the mark. My generosity is known. You will pay with your brain for this attempt at smearing my name. Shooting ass shelling ass bitch. Little bitch kicks from a shell. Good luck when you’re caught. You’re fucked.— Conor McGregor (@TheNotoriousMMA) April 12, 2021Conor McGregor further announced that his trilogy fight against Dustin Poirier was now off, with the Irishman planning to fight someone else.In a paragraph of heavy insults aimed at The Diamond, McGregor tweeted: "You're ripped you inbred hillbilly. 500k with no plan in place. Ye hang tight. Fool. You must be new to money. The fight is off btw. I'm going to fight someone else on the 10th. Good luck on your old contract kid."You’re ripped you inbred hillbilly. Why do you wink with your ears? You fucking brain dead hillbilly. 500k with no plan in place. Ye hang tight. Fool. You must be new to money. The fight is off btw. I’m going to fight someone else on the 10th. Good luck on your old contract kid.— Conor McGregor (@TheNotoriousMMA) April 12, 2021This outburst was in stark contrast to McGregor's previous behaviour. It was as if Conor knew he was better off reviving his 'Notorious' persona. We await confirmation of the fight being off. Until then, the trilogy remains in place.
