Kekeke comes from Korean online writing, where the consonant ㅋ, pronounced like a short k, is repeated as ㅋㅋㅋ to show laughing. Romanised as ke ke ke, it spread through chat rooms, gaming lobbies and early meme culture as a typed snicker. English speaking players picked it up from Korean gamers and began using it as both text and a spoken giggle. It remains popular because it sounds more teasing and secretive than a full laugh, making it perfect for pranks, trolling moments and smug reactions.
