sweet red bean paste
In sumo, very large and heavy wrestlers are sometimes called “anko.” This has nothing to do with sweet red bean paste; the term comes from their round, anglerfish-like body shape. Conversely, thin and slender wrestlers are called “soppu,” a word for “soup,” said to liken them to chicken bones after the broth has been made. Sumo includes these kinds of interesting expressions.
