The German word Ohrwurm, which, is composed of Ohr, ear, and Wurm, worm, and could thus be translated literally as earworm, is used for a melody that sticks in your mind and plays there on a loop. We went to a fast-food sushi shop the other day, where they had a whole CD of pop-music songs praising sushi. The lyrics were along the lines “sushi, sushi, arigato” (“sushi, sushi, thank you”) and similar pearls of wisdom. The tunes were unfortunately very catchy. Now I have a Japanese earworm. Thank you, sushi.
