The sound is based on the well-known “noot noot” vocalization from Pingu, the clay animated children's series. Online, heavily distorted edits like this became popular because they turn a harmless cartoon catchphrase into a loud reaction sound for ironic humor. It shows up in short meme videos, reposts and chaotic edit compilations, often alongside other exaggerated reaction clips such as bruh or goofy ahh sounds. Its staying power comes from being instantly recognizable, short, and easy to place on visual punchlines.
