The phrase comes from everyday Russian slang, where dolbaioby is a crude plural term for idiots, and my means we, making the line a collective admission rather than a single insult. It spread online as a short meme reaction in gaming clips, chat voice notes and edited fail videos, especially in Russian speaking communities. Its brevity, about two and a half seconds, makes it easy to loop or cut into edits. It remains popular because it says what an embarrassed group is already thinking without needing any context.
