The line comes from Deltarune Chapter 2, released in 2021, where Queen repeatedly tells Kris to get the banana for its potassium. Toby Fox built the scene as a running gag during the Cyber World car ride, and fans clipped Queen's voice shortly after launch. The phrase spread on soundboards and short video edits as a standalone command, often detached from the game, because anyone understands the absurd order even without knowing the full quest or characters involved in the scene.
