"Yabba Dabba Doo" is the signature catchphrase of Fred Flintstone from The Flintstones, the animated television series that debuted in 1960. Over time, the line became much bigger than the show itself and spread through reruns, pop culture references, and internet memes. It still shows up in short edits because the phrase is instantly tied to cartoon celebration, goofy confidence, and stone-age humor. Its staying power comes from how fast people recognize it, even when used in modern meme formats.
