Kappa began as a popular emote on Twitch, where chatters used the face to signal sarcasm, trolling and jokes that were not meant literally. The word spread beyond live chat into videos, memes and soundboards as a shorthand reaction that everyone in gaming culture recognised. KogKawa riffs on that same cue as a short audio version, turning a typed emote into a spoken punchline. It stays in use because it is instantly understood, fits almost any playful lie or exaggeration, and needs no explanation for regular stream viewers.
