The Mori Calliope Horse Audio meme stems from a segment in the Hololive VTuber's stream that was quickly taken out of context and paired with unusual horse sound effects. What started as a niche inside joke within the 'Deadbeats' community spiraled into a viral 'cursed' audio trend across TikTok and YouTube. Fans use this template to highlight moments of confusion, shock, or pure absurdity during streams. It represents the chaotic energy often found in VTuber culture, where unintentional sounds or specific vocalizations become legendary internet artifacts.
