The King laugh comes from Clash Royale, Supercell's competitive mobile card battler released in 2016. Players mostly know it from the King's emotes, where the character laughs at opponents during matches. Outside the game, the sound spread through short gaming edits, TikToks and reaction memes because it instantly signals smugness, trolling and lighthearted disrespect. It is still popular because even people who no longer play Clash Royale recognize the laugh, making it a fast shorthand for winning, clowning or getting the last laugh in a clip.
