People who defended Conor's loss against Khabib used the argument that Mcgregor was already rich at the time and wasn't motivated, and stated that "Motivated McGregor" would destroy Khabib. People were so amused by this that they started using the term as a joke to mock McGregor fans, often using the term to describe McGregor in an almost Godlike way.
Motivated McGregor would knock out Mike Tyson with a 360 tornado kick in 5 seconds of the first round.
