The clip circulated as a short meme recording lifted from a YouTube video, where the puking audio was captioned with the OwO and UwU faces it resembles. Those faces come from anime and furry fandom text slang used for surprise and cuteness, which made the gross sound instantly shareable as a joke. It spread through soundboards and short edits as a reaction for cringe and disgust, and it stays popular because the mismatch between cute internet language and vomiting is immediately recognisable even without any context or setup at all.
