Is is a set of erotic tropes where people have extra genders and sexes and go into heat. It can be added to any fanfiction to add some variety and structure.

Of note there is a trope that relates to people going into heat having issues with insurance related to access to healthcare which is just such an amazing artistic note

I saw a report of someone finding a group of japanese fan fic writers trying to understand what is even going on with the American fics. From what I saw the japanese writers could not wrap their mind around the american system and it's failings.
