The Demi Lovato meme landscape is dominated by the legendary 'Poot Lovato' urban legend, which emerged in 2015 from a candid, unflattering photo taken at a red carpet event. Fans jokingly claimed the figure in the photo was Demi's secret twin sister, Poot, who had been locked in a basement her entire life. This absurdist backstory turned a simple bad photo into a global phenomenon, symbolizing the internet's ability to create elaborate lore out of thin air. Beyond Poot, Demi's expressive facial reactions during interviews and social media interactions—including the 'Delete it fat' hoax and her vocal stances on various social issues—have provided a goldmine for relatable, high-energy reaction templates used across TikTok, Twitter, and Instagram.
