The sound comes from Cyriak's Robogran, a piece by the animator known for strange, looping, digitally manipulated creatures and scenes. Lifted as a tiny standalone clip, it began circulating on soundboards and in short-form edits, where its brevity made it easy to reuse. People keep returning to it not for a clear joke or catchphrase, but for the odd, deadpan effect of spelling out goos as if it meant something, a quality that fits surreal meme humour and quick reaction edits.
