The line comes from Heart of a Dog, the 1988 Soviet film adaptation of Mikhail Bulgakov's novella Sobachye Serdtse. Shouted during a chaotic queue scene, it became one of the movie's most quoted phrases in Russian speaking culture. As clips from the film circulated on soundboards and in meme edits, the short insult kept its punch outside the original scene. It now works as a standalone reaction to disorderly lines, impatient crowds and anyone trying to push in first.
