The 'Who Is This Diva?' meme is a versatile reaction template used to highlight high-energy, dramatic, or 'extra' behavior from people and animals alike. While frequently associated with legendary reality TV personalities like Tiffany 'New York' Pollard, the phrase has evolved into a general expression of mock-awe or confusion when someone starts acting like a high-maintenance superstar. It gained significant traction on platforms like TikTok and X (Twitter), where users pair the caption with footage of toddlers having tantrums, cats looking posh, or unexpected celebrity glow-ups. The meme perfectly captures the intersection of sass and bewilderment, making it a staple for commenting on any scene-stealing performance in everyday life.
