The spinning Oiia cat rose through TikTok and meme pages as a deliberately meaningless loop, with creators pairing the chant to a rotating cat image until the phrase became shorthand for brainrot humour. As remixes spread, the hehe ending was kept as the recognisable payoff, separating it from a plain cat laugh meme or other animal clips. It remains popular because the sound needs no context, works muted in captions as text, and instantly signals a joke is intentionally stupid rather than serious or dramatic in tone today.
