Refer to Fujoshi
A rotten girl is a self-mockingly pejorative Japanese term for female fans of manga and novels that feature romantic
relationships between men. Fujoshi enjoy imagining what it would be like if male characters from manga and anime, and occasionally real-life male performers as well, loved each other. The label encompasses fans of the boys love genre itself. Fans self-deprecatingly refer to their way of thinking, which perceives
homosexual relationships between male characters in stories that do not include homosexual themes, as being "rotten". "Fujoshi" carries a connotation of being a "fallen woman"
