Vy cho is a piece of Russian internet slang, a blunt, colloquial way of asking what someone is doing, and it works online precisely because it sounds like a challenge rather than a polite question. The clip circulates on meme soundboards and in Russian-language edits, where it is dropped over fails, pranks, and bewildering choices as a shorthand for disbelief. Like Bruh, it needs no translation to land: the tone alone tells viewers that something has gone wrong, which is why editors keep returning to it for quick reaction moments.
