Dustin Poirier appeared to slap a fan who held up a sign which had the message 'Hey Dustin, your wife's in my my DM's' on it.
Conor McGregor infamously attempted to troll Poirier after their trilogy fight in 2021, claiming that the American's wife Jolie had messaged him on social media.
But the insult didn't really have the desired effect as McGregor was lying on the canvas with a broken leg at the time after suffering his second defeat to Poirier in less than six months.
