The 'Open The Window, Luthor' meme features an image of Superman hovering menacingly outside Lex Luthor's high-rise window, usually taken from DC animated projects like 'All-Star Superman' or 'Justice League'. It exploded in popularity through viral AI-voice parodies where Superman delivers unhinged, persistent, or oddly specific monologues while Luthor cowers inside. The meme perfectly captures the feeling of an unavoidable annoyance, a persistent friend, or an intrusive thought that literally will not go away. It is widely used to represent situations where someone is trying to ignore a problem that is staring them directly in the face.
