This sound is best known from Danganronpa 2: Goodbye Despair, where the body discovery announcement plays when a victim is found and the story shifts into investigation mode. The line became popular in anime and gaming meme edits because it instantly signals suspense, shock and dark humor in only a couple of seconds. It still gets reused in short videos, compilations and parody reveals whenever creators want a dramatic, game-like way to present an obvious disaster or sudden downfall.
