==AUs in Fanfiction==
In fan fiction, an AU refers to a story that diverges significantly from the canon
in the Show. Generally the writer will choose to alter key events in canon (known as the [http://en.wikipedia.org/wiki/Point_of_divergence Point of Divergence (POD)] ) e.g. John dies when Sam is a baby and the boys are raised by Mary, Dean doesn't go to hell, or Castiel falls and becomes human.
Some stories may become AU as new information is later revealed on the Show. This is especially true of stories written between seasons, where a fic is based on certain assumptions of what may occur that are then disproved by later canon (also known as being [[Jossed]], a term coined in relation to Joss Whedon and the Buffy verse). In Supernatural fandom the term [[Kripked]] was coined to describe the opposite phenomenon - when events in fan fiction are later confirmed by canon.
If a story is generally compliant with major events, the introduction of a sexual relationship between characters - whether it's [[Wincest]],
for example, or [[Destiel]], or Gabriel/Balthazar, is not considered to make a story an AU.
Some stories may be set in a totally different universe
(e.g. Sam, Dean, and Castiel are professional bull riders or FBI agents ). These stories more closely resemble original fiction in that the characters share little in common, other than their names and some personality traits, with their canonical versions. These stories are more common in [[RPF AU|RPF]] fics. In [[RPF AU]] stories are essentially original fiction, where the major characters are named, and occasionally very loosely based, on real people.
