The 'Who The Fook Is That Guy' meme originates from the UFC 205 pre-fight press conference held in 2016. In this viral moment, Irish MMA superstar Conor McGregor is interrupted by fellow fighter Jeremy Stephens, who claimed he was the hardest-hitting 145-pounder in the organization. McGregor instantly responded with the iconic, dismissive line delivered in his thick Irish accent while gesturing toward Stephens in mock confusion. The audience erupted, and the moment was instantly etched into sports history. This clip is now the gold standard for internet 'clout-checking' and dismissal. It represents situations where someone of high status is challenged by someone they deem irrelevant or unknown. It is commonly used to express feelings of superiority, genuine confusion, or calculated disrespect toward a challenger or a random social media commenter. Example captions include: 'When a random relative tags you in a post from 2012,' 'My bank account looking at the $200 checkout screen,' and 'When a coworker you have never met tries to tell you how to do your job.'
