Deltarune is Toby Fox's episodic role-playing game, and its Weird Route, also called the Snowgrave Route by players, is the secret alternate path in Chapter 2 where the player pushes the story in a darker direction. Clips of that route circulated widely among fans, and the short jingle became shorthand for the route itself in edits, memes and theory videos. It remains popular because it instantly signals that a playthrough has left the normal story behind, without needing any explanation.
