Yiff


 * "You know, I only took *three days* [vacation] after the Aragorn/Brego slash." &mdash;Rhus Radicans, "Broken Doll"

Yiff is defined as pornographic material involving anthropomorphic animal characters (generally known as "furries"). This is not especially common in fanfic as few continua involve such characters. Most yiff fiction is original fic produced by the furry community. When it shows up in fanfic, it is almost invariably in fandoms where the original work is aimed at children (e.g. Disney), since they are the most likely to feature anthropomorphs, and is in the majority of cases intended as mockery of the fandom rather than a serious fic.

May also be used to describe scenes involving non-anthropomorphic animals, such as those in "Cho Chang's Desires" or "Celebrian," though human-animal intercourse is more accurately referred to as bestiality. A key difference between the two is that furries have human sapience and can give consent; non-anthro animals usually don't and can't.

Bad yiff often includes very bad biology and usually a lot of squick, even for those who actually like furry characters. In fact, especially for those who like furry characters, because they often remember the victim characters from their childhood favourite fandoms. See Rule Thirty-Four.

Fics of this category include:


 * That Series and the "Lion King Orgy Poem"
 * "Land Before Time: Littlefoot x Cera"
 * The works of Chaser Wolf
 * "For Your Eyes Only"
 * "Forbiden Fruit" has a brief scene in which Jasper Cullen has sex with a panda.
 * "Mouse mating" in which a Pixie Hollow fairy is sodomized by a mouse.
