Destroy your fanon is when you insert fanon into an article on a humor wiki, like Wookiepedia the English Star Wars Humor Wiki, and it gets reverted by special wizards known as "Administrators". Then you do it again. And again. And then you are banished by the "Administrators"...FOREVER! So...go to the fanon wikis, like this one or this one. Trust me, they love fanon.
