The exact origin of this tu ta ta recording is unclear, but its appeal online comes from how easily the chant works as a ready made rhythm track. Short looping syllables like these spread through meme pages and soundboards because they can be dropped onto almost any clip without needing context or lyrics. The repeated pattern is instantly recognisable after one listen, which helps it stick in edits, remixes and reaction videos where timing matters more than a full song or a recognisable line of dialogue.
