MiSide is an indie horror adventure game released in 2024, built around Mita, a seemingly sweet virtual girl who becomes the focus of the story. Clips of her voice lines spread quickly on video platforms and soundboards, especially short lines that work out of context. This Portuguese phrase, which translates to my butt is hurting, became a shareable reaction separate from the game's darker scenes. Its popularity comes from that mismatch, letting a horror character be heard in a harmless, funny moment that creators can drop anywhere.
