Let us presume, for a minute, that fanficcers are not writing fanfiction but making sandwiches.
(I know. There is not a lot of correlation between fanfiction and sandwiches, not least of which because you can't upload a sandwich to the Internet no matter how hard you mash it against your modem. All you get is a mess and, if you keep on doing it, a broken modem. Please, bear with me.)
Context has much more, including scenes at Helga's House of Doing Interesting Things With Bacon.
