Kappa is the global face of sarcasm on the internet, originating from the live-streaming platform Justin.tv, which later became Twitch. The image features a grayscale photo of Josh DeSeno, one of the platform's original employees. Since its debut around 2009, the emote has been used billions of times to signify irony, trolling, or a 'just kidding' sentiment at the end of a sentence. It has transcended Twitch culture to become a universal symbol for internet snark, often appearing in forums and social media whenever someone is being less than serious.
