The Dr. Simi at Concerts phenomenon began as a spontaneous gesture in Mexico and quickly evolved into a mandatory ritual for international artists visiting the country. It involves fans throwing plush dolls of the Farmacias Similares mascot, Dr. Simi, onto the stage as a token of affection and a warm Mexican welcome. What started with a doll thrown during an Aurora performance in 2021 has since seen icons like Adele, Rammstein, and Lady Gaga receiving their own custom-dressed Simi dolls. The meme represents the vibrant and unique fan culture in Latin America, often used to joke about an artist's official initiation into the Mexican music scene or to celebrate the mascot's unexpected global fame as a concert staple.
