The oiiaoiiai sound grew out of short-form cat meme culture, where looping animal clips are remixed again and again until a single noise becomes shorthand for a joke. It spread mainly through TikTok and Instagram edits pairing the vocalisation with spinning cats, dizzy turns and absurd transformations, and its simple spelling made it easy to search, caption and repeat. Like the cat laugh meme, it works because it is instantly recognisable, endlessly loopable and funny without needing any explanation, which is why editors still reach for it for quick chaotic punchlines.
