Fanfic

From Fandom wank wiki

Fanfic (short for fan fiction) refers to any and all fiction written for the purpose of fandom. Fanfic stories can be about movies, TV shows, cartoons, comic books, book books, video games, real people, other people's fan fiction, and much much more. If you're a fan, and you can write, you can write fanfic. (The second condition is optional.)

Fanfic is typically written to tell stories that can't or wouldn't be officially told in the fandom's canon (or in the case of RPF, real life). It is often used to expand upon (or invent) romantic relationships between characters or to create an unofficial canon. By definition fan fiction lacks the structure found in its source material, leading to wank within a fandom about the types and quality of stories.

"Fanfic" may be further truncated to just "fic," as seen in more specific terms like "slashfic," "genfic," "badfic", etc.

Most fanfic can qualify as porn. Well, according to Lee Goldberg, anyway. For more variations, please check Every Fanfic Ever Written.
