This sound comes from Clash Royale, the mobile game by Supercell released in 2016, where the King appears in emotes and reactions during matches. The crying version became especially recognizable in meme edits because its high-pitched, whiny delivery is easy to loop and instantly communicates exaggerated sadness. Online, people often refer to it as the Clash Royale King crying sound or write it out as mimimimimimi. It remains popular because it is short, game-related, and perfect for comedic overreactions after small losses or embarrassing mistakes.
