Mellstroy, whose real name is Andrey Burim, is a Russian-language streamer whose loud, provocative broadcasts have made his reactions widely shared as short clips. This phrase, idi na, is Russian for go to, and it circulates in its clipped form as a dismissive meme sound rather than a complete sentence. Russian TikTok and short-form editors reuse it to punctuate arguments, roasts and reaction videos, keeping it alive because the tone alone carries the joke even for viewers who do not speak Russian.
