During the conversation, O’Malley said:
“His ass is bigger than a Miami b*tch’s BBL. It was mind-blowing. Holy sh*t. If I didn’t know better, I might’ve f*cking jacked off. It was huge. I looked at his butt for like 7 seconds.”

The comments instantly spread across social media, with many MMA fans laughing at O’Malley’s brutally honest description of the situation.
Pereira has always been known as one of the most physically intimidating fighters in the UFC. Standing at around 6-foot-4 with massive power and an unusually large frame for a combat athlete, the Brazilian knockout artist often looks far bigger than many of his opponents inside the cage.
Even fighters from heavier divisions have spoken before about how imposing Pereira appears in person.
Since moving from kickboxing into MMA, Pereira has rapidly become one of the UFC’s biggest stars thanks to his knockout power and calm personality. The former two division UFC champion built his reputation through devastating finishes and victories over elite opponents across both middleweight and light heavyweight.
O’Malley, meanwhile, has developed a reputation for mixing serious fight analysis with unpredictable humor during interviews and podcasts. His personality outside the cage has become a huge part of his popularity, especially among younger MMA fans.
The reaction online to his Pereira comments has mostly been humorous, with fans joking that O’Malley gave one of the funniest fighter descriptions of the year.
While Pereira himself has not publicly responded yet, many fans would probably not be surprised if the Brazilian simply laughed it off. Known for his relaxed personality outside competition, Pereira rarely seems bothered by unusual comments or social media attention.
For now, though, O’Malley’s unexpected description of seeing Pereira up close has already become another viral MMA moment.
