Eto dollary is the transliteration of a short Russian phrase meaning these are dollars, circulated online as a standalone meme sound rather than as part of a longer recording. Its appeal comes from how recognisable the word dollars remains for English speaking listeners, even when the rest of the line is in Russian. Short voice clips like this travel easily between edits, chats and soundboards because they need no context to set up and only a second to deliver. It is now mostly dropped into money related jokes, where the foreign phrasing makes a simple brag feel deliberately exaggerated.
