The "└[ó0ò]┘" emote, also known as the "A surprised square dude" emote, is a text-based emoticon that represents a surprised or shocked face. It consists of a square-shaped head with wide open eyes and a mouth that appears to be shouting or gasping in surprise. The two diagonal lines on either side of the head represent raised arms or hands. The emote is often used in online communication to express surprise, shock, or disbelief.
