KEKW is closely tied to Twitch culture and comes from the laughing face of Spanish comedian El Risitas, whose interview clips became a long-running internet meme. The emote version spread widely on Twitch around 2019, especially in gaming streams and chat reactions. As a sound, the laugh is used to mark moments that are hilariously scuffed, badly timed or impossibly dumb in the best way. It remains popular because viewers immediately recognize the tone and associate it with live reactions, spammy chat energy and shared meme language.
