Quidditch in Bed
From Fan History Wiki
Quidditch in Bed is an imaginary sex manual held to be a typical product of Gryffindor House. It was invented by Textualsphinx in her ficlet Why Slytherins Are Sexier, and was soon established as a kind of fanon bibliographical 'fact' that was cited in various fictions such as Riley's Pawn to Queen and Theatresm's Brave New World. Textualsphinx eventually challenged the fandom actually to write Quidditch in Bed, a challenge that was met by Angel of the North.
Of interest, Quidditch in Bed was conceived of long before J K Rowling had Harry kiss Ginny in the afterglow of a successful game of Quidditch.
