The term crack is used to signify stories that are so strangely insane they can only be written and read under the influence of heavy drugs, i.e., you'd have to be on crack cocaine in order to think up things like this. Of course after being in fandom for a while, many of these ideas seem perfectly normal.
The relationship between fans and Crackfic, too, is one of a loving addiction.
'Crackfic' is less a genre of fanfiction and more a categorisation based on its premise. 'Crackfic' is fanfiction whose scenario is a marked departure from the reality of the original text (in this case, Supernatural).
Crackfic is a thriving genre in Supernatural fanfiction, arguably because of the permissability permissibility of the canon, wherein these out-of-the-ordinary things happen as a matter of course.'Crackfic' is named thus due to the outrageousness of the premises it depicts - i.e. you'd have to be on crack cocaine in order to think up things like this.
This list was started in 2006, when fandom was small. Obviously the number of fics in these categories now is huge. To find more recent examples visit [[Rec Communities]].
There are a number of cliche crack scenarios that make the rounds of any number of fandoms, such as [[Genderswap]], [[Bodyswap]], [[Animal Transformation]], [[Sex pollen]], etc.
A number of these scenarios have ended up as [[Canon]] - to find out which ones see [[Kripked]]
Gender Swtich Swap fics cover a wide range of situations. Most often a curse/supernatural being turns a character into the other gender temporarily. There are also fics where one of the chacrters was always a different gender - for example see [[Winsister fic]]. Finally, there are a few fics where a character is transgendered.

We've all read fic that made our brains ache, but that usually wasn't the author's original intention. bad!fic is a genre of purposefully horrific fic. These stories set out to assault the reader with horrendous pairings, clusters of cliches and general abuse of the language.You've been warned!
