UFC veteran Donald Cerrone and CM Punk took part in a special Fan Expo Q&A, which was dubbed the "UFC 200 Aftermath." One fan asked both men what their favorite fight of International Fight Week was, with Cerrone going with Joanna Jedrzejczyk vs. Claudia Gadelha, while Punk opted for Jose Aldo vs. Frankie Edgar (which CM Punk scored for Edgar, but we'll save that for another day).

The conversation took a sharp turn when Cerrone changed the subject to the worst fight. Here's their back-and-forth on Daniel Cormier's win over Anderson Silva.

Cerrone: "What about the worst fight?"

CM Punk: "The worst fight?"

Cerrone: "Your boy, DC. Terrible!"

CM Punk: "What?"

Cerrone: "Terrible. How are you going to give up weight and then fight like a f*g, man?"

*applause breaks out in the audience*

CM Punk: "Wait a second. You and everybody else who clapped for that were the same people who were cheering when Brock would take Hunt down, and do the exact same thing DC did to Anderson."

Cerrone: "That's different. That was Brock."

CM Punk: "It's the same thing!"

Cerrone: "Yeah but Anderson is giving up 30 pounds, flies in, two days notice, fights [Cormier], you're -- f*cking stand and fight, motherf*cker!"

CM Punk: "Hey, I get it! Everybody's disappointed. They want to see Anderson Silva do some ninja shit. But if I'm standing across from him, I don't want to see him do ninja shit. I'm gonna take his ass down."

"Cowboy" has been in trouble in the past for using the homophobic slur. In 2010, in an interview conducted by Bloody Elbow's Stephie Haynes on Tapout Radio, Cerrone said of Jamie Varner, "He's really a f*g. I mean, that's what he is, you know, and his true colors will show up," and later retracted a statement that he hoped his win over Varner would be the first death in MMA.

Cerrone's statement today comes just days after the UFC released its "We Are All Fighters" shirt, with all proceeds going to the LGBTQ Center in Las Vegas, and hours after Amanda Nunes became the first openly gay fighter to win a UFC title.
