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.

SYNONYMS:

Smut
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.
