McGregor is “Notorious” for his trash talk, never wasting a chance to fling some insults at his opponent.
Whether it’s at press conferences, weigh-ins, walking into fights, during fights, or after fights, McGregor always has something to say—sometimes even going over the line. Things got extremely heated during the lead-up to his rematch with Nate Diaz at UFC 202, with McGregor hurling insults and bottles as Diaz’s crew, which resulted in a hefty $150,000 fine and some trash talk thrown in the direction of the Nevada State Athletic Commission.

McGregor’s trash talk isn’t just for show, though: He often uses it to get into his opponents' heads, and often it works. The outspoken fighter was constantly playing mind games with Jose Aldo leading up to their fight, which ended up as the fastest knockout in UFC history at just 13 seconds by McGregor. The Irish fighter uses his words as weapons, just like his fists.
