Yaoi is a term used to describe adult themes and graphic materials centering on romantic relationships between two (or more) males (always NC-17+ rated). Yaoi is actually a Japanese acronym shown below.

YAma nashi (Without climax)
Ochi nashi (Without conclusion)
Imi nashi (Without content)

Yaoi is basically a PWP. Like the components that make up its name, yaoi does not have a point, meaning, or end (seemingly), seeing as it is, most often, just graphic sex, and, in no ways limited in explicit descriptions of foreplay.

Some can argue that yaoi is not meaningless. However, yaoi is often utilized in shounen-ai pieces, which concentrate on the plot. Yaoi, itself, is the detailed description of the sexual process, which can be easily left out of the piece without changing the depth of the story. Still, it is according to preference whether one would want to read/see a simple lime or a full-blown lemon. Of course, there are people who favor plain shounen-ai.
This fanfiction is shounen-ai, as Male #1 and Male #2 are attracted to each other. Warning: This story contains YAOI, as Male #1 and Male #2 will have graphically-described sex with each other.

An anime and manga slang that is used to refer to ''Gay'' or ''boy-to-boy'' relationship. Whilst this is something you wouldn't expect to be so popular... It is. The opposite of Yaoi is Yuri which means ''Lesbian'' or ''girl-to-girl''. Yaoi consists 95% of the time out of graphic fanfics.

14 Year old girl: Ah... Nothing... Was just reading some Yaoi mangas.

Japanese for Guy x Guy or Guy on Guy love a.k.a. male coupling. Yaoi is the coupling of any male of any kind. Including: Anime, Manga, reality, Books, Video Games, Movies, etc. Related to Yuri: Girl x Girl/Girl on Girl and Shonen-ai: Yaoi but with a little less "action" per say.

Yaoi is a popular term for female-oriented fictional media that focus on homoerotic or homoromantic male relationships, usually created by female authors. Originally referring to a specific type of dōjinshi parody of mainstream anime and manga works, yaoi came to be used as a generic term for female-oriented manga, anime, dating sims, novels and dōjinshi featuring homosexual male relationships.

Yaoi began in the dōjinshi markets of Japan in the late 1970s/early 1980s as an outgrowth of shonen-ai. BL (Boys Love, another term for yaoi) creators and fans are careful to distinguish the genre from “gay manga,” which are created by and for gay men.

The main characters in BL usually conform to the formula of the seme who pursues the uke.
Yaoi is what keeps fans going.

a male/male type of hentai that anime fangirls (and some boys) like to watch. homosexuality within anime that is fanmade (90% of the time). it is very graphic and usually has sexual content not meant for people under 18.... but more 12-15 year olds watch it more than anything lol. Yuri is the opposite of Yaoi which has female/female hentai.
yaoi is badass. yuri is not.

Yaoi is male/male love, it does not have to mean sex; it just means "gay anime" as most used to call it.
