Podfic is an audio recording of Fanfiction, read aloud by a fan (or several). The term is also used as a verb; someone may ask to podfic someone else's story, or spend an afternoon podficcing. A podfic of a slash story may be called podslash. Podfic is also known as audiofic. A fan who produces podfics can be called a podficcer, a podfic reader, or a podfic artist. Some such people have strong feelings regarding this designation.
Sometimes fans podfic their own stories; however, most podficcers read stories by a variety of authors. It is customary to ask permission before podficcing someone's else's story, probably due to the unwritten fannish rule that dictates not archiving other people's stories without their permission.
