Ero guro nansensu, frequently shortened to ero guro or just guro, (エログロ ero-guro) is a literary and artistic movement originating c. 1930 in Japan. Ero guro puts its focus on eroticism, sexual corruption, and decadence. While ero guro is a specific movement, many of its components can be found throughout Japanese history and culture.The term itself is an example of wasei-eigo, a Japanese combination of English words or abbreviated words: ero from "ero(tic)", guro from "gro(tesque)", and nansensu from "nonsense". In actuality the "grotesqueness" implied in the term refers to things that are malformed, unnatural, or horrific. Items that are pornographic and bloody are not necessarily ero guro, and vice versa. The term is often used incorrectly by western audiences to mean "gore"—depictions of horror, blood, and guts.
