Goo goo ga ga has been shorthand for baby talk in English for generations, long before short-form video turned it into a reusable audio gag. Online, the gugu gaga clip spread as a standalone meme sound rather than a line from a known film or show, passed around on soundboards and in edit packs. Creators pair it with a baby laughing meme or use it alone to label someone as helpless, adorable, or not making any sense. Its appeal is instant recognition, no setup is needed for viewers to understand the joke.
