The line comes from UFC 205 on 12 November 2016 at Madison Square Garden in New York, after McGregor stopped Eddie Alvarez in the second round to win the lightweight title. Already holding the featherweight belt, he became the first UFC fighter to hold two titles at the same time. His post-fight speech, delivered to a roaring Irish crowd, was clipped and shared across YouTube, TikTok and sports pages, where it became shorthand for unapologetic confidence. It still appears in victory edits, football celebrations and comeback montages because the delivery is instantly recognisable.
