SourPls is one of the most recognizable animated emotes on Twitch, featuring a man dancing energetically in what appears to be a Toys "R" Us store. The original footage originates from a 2007 YouTube video titled "Sour," featuring a user known as SourVids. It transitioned into internet legend status through the BetterTTV (BTTV) browser extension, which enabled the animated GIF to play in Twitch chats whenever the phrase was typed. It is primarily used when high-energy music is playing during a stream, serving as the universal digital sign for vibing, celebrating, or simply losing oneself to the rhythm.
