In Japan, where this word comes from, hentai translates to "pervert", "strange", or "weird" in English. In the western world, it is used to refer to any form of drawn or animated pornography originating from Asian regions, especially those from Japan as well as the particular anime style art associated with it. It is also used to refer to non-Asian drawn/animated pornography in the same style as well, but terms like "rule 34", "NSFW", "lewds", or just "porn" are more often used there.

Do not use this tag as it is too broad of a term.
