The "•|龴◡龴|•" emote, also known as the "Smug" emote, is a popular emoticon used in online communication to express a sense of satisfaction or smugness. It consists of a face with raised eyebrows and a slight smile, surrounded by two hands forming a "U" shape on either side of the face. The emote originated from a Japanese manga series called "K-On!" and has since become widely used in various online communities.
