The chant comes from Mickey Mouse Clubhouse, the Disney Junior series where Mickey summons the clubhouse by saying Meeska Mooska Mickey Mouse. Online editors later turned that wholesome moment into earrape, a meme style that deliberately distorts familiar audio to an uncomfortably loud, clipped level for comic shock. Shared through YouTube edits, TikTok videos and soundboards, the clip became a shorthand for absurd, over-the-top reveals. It stays popular because almost everyone recognises the original chant, so the distorted version lands instantly without any explanation.
