Ailin Perez, an Argentine UFC bantamweight fighter, secured a first-round submission victory over Darya Zheleznyakova at UFC Paris, despite missing the bantamweight limit by 0.5 pounds the day before. Following her win, Perez celebrated by twerking on her fallen opponent, a gesture that drew mixed reactions from the MMA community. Perez explained her actions as a response to trash-talk from Zheleznyakova prior to the fight. The celebration, which has become Perez's signature move, was criticized by some, including former UFC champion Aljamain Sterling, as disrespectful. Despite the controversy, Perez's victory extended her winning streak to four consecutive fights, and her UFC ranking remains at No. 15. The incident has garnered significant attention, further increasing her social media following.
