After Ronda Rousey lost to Holly Holm at UFC 193, Donald Trump was one of the many celebrities to talk trash about her. He took to Twitter to say that she is “not a nice person.”

X17 Online caught up with Conor McGregor earlier today and asked him about the Rousey/Holm fight as well as what he thinks about people like Trump talking trash. And he let it be known that he doesn’t appreciate the hate that has been directed at Rousey.

“It’s easy for someone who isn’t in [the Octagon] to comment,” he said. “It’s different when you’re in there. The emotions are high. It is what it is. You either want to touch gloves or you don’t. Donald can shut his big fat mouth. I don’t give a fuck about Donald Trump.”

Well then. Why don’t you tell us how you really feel, champ? Check out the clip above to hear McGregor go off. He’s scheduled to fight Jose Aldo at UFC 194 next month.
