Used in various online fiction, fan fiction, and erotica, these are short groups of abbreviations that tell the reader what the story will feature. For example, in erotic stories found online, the code for adult male is M and the code for adult female is F, thus stories that feature a man and a woman engaging in some sort of sexual situation would initially be labeled as MF. If it were a lesbian pairing it would be FF and if it were some sort of threesome or other imbroglio, FFM or MMF would be used.
As well, the specific activities engaged in are usually noted, i.e. the code for exhibitionism is exhib, the code for oral sex is oral. Thus, FM+, bd, fist, hist would mean a woman and multiple men participating in bondage and discipline and fisting in a historical time period.
Index to the Content Codes:

Willingness or unwillingness
Dominance, submission, bondage, pain and violence
Relationships

Special codes for MM and interr stories
Musts (codes considered very rude to omit)
All applicable keywords could (and should) be used to describe the story, regardless of the level of their inclusion; although petting and oral sex are so frequently a prelude that their codes may be omitted when they serve as a prelude. It would be a politeness though, if the code for the essential theme in the story appears early on. Traditionally, the codes for sex, age, and number precede the others.
NOTE: It's considered extremely rude to include the categories marked
with an asterisk (*) below without warning of them in the story codes.
