“Since at least the 18th century (in French and German as well as English), grotesque has come to be used as a general adjective for the strange, mysterious, magnificent, fantastic, hideous, ugly, incongruous, unpleasant, or disgusting, and thus is often used to describe weird shapes and distorted forms such as Halloween masks. In art, performance, and literature, however, grotesque may also refer to something that simultaneously invokes in an audience a feeling of uncomfortable bizarreness as well as sympathetic pity.” (from Wikipedia)
