Pop Cat spread online in 2020 from short edited clips of a cat opening and closing its mouth to make a popping sound, quickly becoming a reaction meme and rhythm game format. This yeayeayea version layers an excited chant over the pops, turning the simple loop into a more frantic soundboard staple. Creators reuse it on TikTok, Shorts and Discord because the pattern is instantly recognisable even without the image, and the relentless repetition works as a shorthand for goofy excitement, teasing friends, or mocking something cute and over the top.
