Static writes: Is Taboo considered a genre that should be used as a general description for manga sites that contained taboo typed manga books? Also, could you give me a perfect but brief (short) definition of the “TABOO” that I cold use to describe the genre if it were to be used as a general – common – genre type. This isn’t my area of expertise, but I thought I’d weigh in anyway. A taboo is a strong social prohibition on activities or customs that are considered sacred or forbidden. The term comes from Polynesia where it’s context was religious. Most taboos have a religious connotations, they can affect dietary restrictions, sexual activities and/or relations, bodily functions, exposure of body parts or offensive language. Taboos are not universal, but many cultures may share some, such as cannibalism and incest. Taboos can change over time, as a society or culture changes.
