Fanfic

A godforsaken piece of fan-based literature ripping off the characters (and possibly storylines) of already copyrighted series in order to make two characters hook up despite how wrong or unlikely said relationship is in the actual series.

Usually crappily done, at least by the author of this page's opinion. (The author's opinion can be deemed credible since she is a journalism major and a published writer at that.)
