2) An erotic or adult fan-story about an anime or videogame character which was written by some sick pervert for the purpose of providing wank material for the Wapanese and the fanboy otaku who frequently attend cosplay conventions.
1) Lemon beverages are a popular drink during the summer.

2) The fanboy had a staggering collection of lemons on his shelf, next to the crate of hand lotion and 12-pack of toilet paper.

Usually a sexually-orientated fan-work or fanfiction, mostly based on manga, anime, video games, and sometimes cartoons. It's also rated 18+ for the sexual acts. It's not like people listen anyway, I don't.

Usually written by women for women, and is about 90% yaoi. There's a difference between porn and lemons, as porn is usually plot-less and has different sexual acts that please men, while lemons are usually written in a book, comic, fanart, or fanfiction. It has more of what pleases women, such as more romance and moar men in it.

Pro-tip: NEVER look up lemons of your childhood favorites. It will shatter your brain.
Pro-tip #2: Most lemons can be found on DeviantART, Fanfiction.net, and just about every other site where horny, sex-crazed teen girls go.


Lime (more romantic and loving instead of sexual)
Ooh, that yaoi lemon I read earlier today was yummy! Mmm... Yaoi...

That FrancexUK story I read earlier today was WAY steamier than the AmericaxUK one I read yesterday.
