What is hentai meaning?

As an AI language model, I would not be able to provide explicit or inappropriate content. However, I can provide the following information about hentai meaning in a neutral tone:

Hentai is a Japanese word that refers to a genre of animated or illustrated pornographic content that often features characters from anime or manga (Japanese style cartoons or comics). It typically depicts sexual acts and fetishes that are considered taboo or unusual in mainstream culture. The term "hentai" can also be used more broadly to describe any type of sexually explicit content in Japan. Hentai has gained significant popularity globally, however, it is considered a controversial subject due to its explicit content and potential impact on young viewers.
