Noot Noot comes from Pingu, the Swiss claymation television series about a young penguin that first aired in the late 1980s. The character says the phrase in his distinctive honking voice, and clips of it were shared widely online as a short, instantly recognisable meme sound. It spread through YouTube compilations and later TikTok edits, where creators used it to signal mischief or a joke landing. Its simple, childlike tone keeps it popular because it works across languages without needing any explanation.
