Slash fiction is a genre of fan fiction that focuses on the depiction of romantic (and often sexual) relationships between two or more male characters, who may not be engaged in relationships in the canon universe. While the term was originally restricted to stories in which one or more male media characters were involved in an explicit adult relationship as a primary plot element, it is now more generally used to refer to any fan story containing a pairing between male characters. The term is also sometimes applie.
