Genderswap, or sometimes also "Genderfuck", means any kind of story in which a character changes his/her gender.
The convention is to refer to the characters as Girl!Dean or Girl!Sam. There are two main types of fic in this genre either Sam and/or Dean waking up as a girl as a result of some supernatural intervention, or stories where either Sam and/or Dean have always been female. A handful of stories are actually about a character being transgendered.
See the Crack page for a list of Genderswap stories.
