This sound is associated online with the “Chipi Chipi Chapa Chapa” or “Dubidubidu” meme, which spread widely through TikTok, YouTube Shorts, and reposted cat edits. The audio comes from the song “Dubidubidu” by Chilean singer Christell, originally released in the 2000s, and it found a huge new audience through looping animal videos. Its staying power comes from the instantly recognizable vocal hook, which fits short repeatable clips and exaggerated cute or chaotic visual jokes.
