The noot comes from Pingu, the claymation penguin created by Otmar Gutmann, whose beak honk became his catchphrase in the series that began in the late 1980s. Because Pingu speaks no real language, the sound travelled easily online, turning into reaction clips, remixes and text posts written simply as noot noot. Louder, distorted versions later spread on meme soundboards and short video edits, where the joke is the sudden volume from such a small, cheerful character, keeping the call recognisable decades after the show.
