Goo goo gaga is a familiar imitation of infant babbling, and short clips like this circulate online as lighthearted reaction sounds rather than as lines from a specific show or film. Creators tend to reach for it when a moment needs instant cuteness, gentle chaos, or a playful baby voice without any real words getting in the way. Its appeal is in its simplicity: anyone recognises the sound immediately, so it works across languages and audiences, and its brief length makes it easy to drop into memes, shorts, and family edits.
