The phrase goo goo ga ga has long been used as playful shorthand for baby babbling, and clips like this one are shared online as cute reaction sounds rather than as part of a film, song or television show. Frankie appears here as the baby behind the voice, giving the sound a personal, homemade feel that fits short social videos. Its popularity comes from that simplicity, as creators reuse it to add innocence, warmth or gentle humour to family edits, pet videos and lighthearted memes.
