RPF and/or RPS

RPF and/or RPS = Real Person Fiction and/or Slash 

Refers to stories featuring the actors themselves (rather than the characters they play) or some other real life person, celebrity, or historical figure. If RPS, those real people are placed in a homosexual relationship. This genre is frowned upon by many fandoms, and many archives and moderators refuse to permit it to be posted. However, some fandoms not only permit it, they even welcome it -- Lord Of The Rings and Supernatural for example. All bandoms (fandoms about musical bands) and sports fandoms (Hockey, etc...) are automatically RPF or RPS by default. Occasionally, RPF or RPS elements may also intersect with fanfiction universes as well, if a real life person is written prominently into a fictional world. Remember, this topic is a highly-debated issue in many fandoms, and a major squick for many people, so it should be listed in the author's warnings. Check with your fandom's communities and archives' rules prior to posting RPF or RPS just in case.
