Slash fiction is a genre of fan fiction that focuses on interpersonal attraction and sexual relationships between fictional characters of the same sex. While the term was originally restricted to stories in which male media characters were involved in an explicit sexual relationship as a primary plot element (also known as "slash" or "m/m slash"), it is now used to refer to any fan story containing a pairing between same-sex characters. Many fans distinguish female-focused slash as a separate genre, commonly referred to as femslash (also known as "f/f slash", "femmeslash", "altfic" and "saffic"). The characters are usually not engaged in such relationships in their respective fictional universes.
It is commonly believed that current slash fanfiction originated within the Star Trek: The Original Series fan fiction fandom, with "Kirk/Spock" stories – generally authored by female fans of the series – first appearing in the early 1970s. The name arises from the use of the slash symbol (/) in mentions in the late '70s of K/S (meaning stories where Kirk and Spock had a romantic [and often sexual] relationship) as compared to the ampersand (&) conventionally used for K&S or Kirk and Spock friendship fiction. For a time both slash and K/S (for "Kirk/Spock") were used interchangeably. Slash later spread to other fandoms, first Starsky and Hutch, Blake's 7, and The Professionals, then many others, eventually creating a fandom based around the concept of slash. Many early slash stories were based on a pairing of two close friends, a "hero dyad" or "One True Pairing" such as Kirk/Spock or Starsky/Hutch; conversely, a classic pairing between foils was that of Blake/Avon from Blake's 7.
