Porn (or Smut)

Porn (or Smut) 

Refers to stories or scenes of graphic sex, in which any plot or character development that also occurs is incidental to the sex itself. The term "smut" is most often used to denote adult stories containing an m/f relationship rather than slash (m/m) stories, while the term "porn" (or "pr0n" in L33t Speak) goes either way, however they are synonymous and interchangeable.
