Conor McGregor was not thrilled when a bystander suddenly threw their bucket hat at him while he was in the midst of celebrating his 34th birthday in Ibiza last week.
A clip from the party showed the MMA legend partying it up in a lush beach club when he was suddenly hit with the black cap.
McGregor almost caught it but it fell to the ground. He then sarcastically smiled at the guy and gave him a thumbs up.
The UFC star then stomped on it before staring the guy down.
McGregor has yet to return to the Octagon since suffering a gruesome leg injury last July in UFC 264.
