The audio comes from a performance by Mexican actress Itati Cantoral singing to La Guadalupana, a beloved figure in Mexican Catholic devotion, and the Spanish caption joking that the devil entered her while she sang turned the moment into a meme. Shared widely in Spanish-speaking social media and soundboards, the clip is now used far beyond its original devotional context, mainly as a humorous reaction to sudden chaos or exaggerated behaviour. Its appeal lies in that recognisable switch from sincere singing to wild, uncontrolled sound, which viewers instantly understand even without knowing the original performance.
