The exact origin of the Tucu clip is undocumented, and no famous film, show, or artist has been tied to it. Like many sounds with cryptic one-word titles, it appears to have surfaced through user uploads on meme soundboard communities, where listeners saved and replayed it purely for its odd, catchy feel. Its spread has been quiet but steady: a few dozen plays here and there, picked up by editors who collect obscure stingers. It endures because short, strange, nameless sounds are endlessly reusable, fitting any joke without carrying baggage from a known scene.
