Hentai
Hentai is a subgenre of Japanese manga and anime built around sexually explicit imagery and plot. The word itself predates the internet, tracing back to Meiji-era Japan before it shifted to its modern erotic meaning after WWII. By the early 2000s the genre grew into a huge presence on image boards, subreddits, and adult art platforms.
Overview
The label covers a broad range of adult anime and manga, from single-image illustrations to full animated features and doujinshi fan comics1. English-speaking fans often shorten it to 'ecchi' for milder erotic material, a pronunciation that Mark McLelland traced to a wartime clipping of the word down to 'H' during the U.S. occupation of Japan3.
Subgenres like lolicon, tentacle art, and yaoi each pull their own fanbases and drawing conventions. Art styles run from detailed doujinshi work to the exaggerated big-eyed look Urban Dictionary contributors joked about as instantly recognizable5. DeviantArt alone lists over 139,000 works tagged with the word, which gives a rough sense of how much fan output the category draws2.

How to Use This Meme
Online, hentai is typically used both seriously as a genre tag on art sites and jokingly in ironic replies about anime fandom. Common convention includes tagging fan art on booru-style image boards, uploading to DeviantArt with the label2, and posting in dedicated NSFW communities like Reddit's /r/hentai4.
