Conor McGregor suffered his first UFC loss when he tapped out during a fight against Nate Diaz in March of this year.  As you know, McGregor and Mayweather are having a war of words over a fight between them that’ll probably never happen.  Mayweather decided to taunt the Irish fighter by posting a video of his submission to Diaz on his Instagram account and offering $10,000 to whoever comes up with the best caption.
