Short for doujinshi. Officially it means any independently published manga, but it's widely used around the interwebs to refer to hentai works.

Japanese word which literally means a group of people with the same interests, but it is often used as a shorthand for doujinshi.

Fan-made published versions of anime/manga. Almost always involves porn. The best one I can recommend to those new to these are Itachi x Sasuke, they make a hot yaoi couple.

Some doujins don't keep true to the original art style though. Stay away from those ones as they are stupid. Only doujins with the same art style (meaning they could be mistaken for the real thing) are acceptable!!
I've been reading doujin. I like the ones with Sasuke and his brother Itachi when they fuck and it shows them all naked and having sex.

Dōjin is a japanese word which is used to describe a group of people with same interests. here is it's kanji (同人). please get don't get it confused with Dōjinshi (同人誌) which is used to describe fanmade works which are created by people who have similar interests. while you may see these words used to describe Hentai manga but keep in mind that this is the traditional definition
Josh: I like that Doujin music alot!

james: yeah, me too!
