SOMEONE ELABORATE PLEASE
The abridged version? There was a Harry Potter fanfic written called My Immortal that was so incredibly bad that everyone kinda loves it. The lead is a goth girl named Ebony Dark’ness Dementia Raven Way and she ends up dating Draco Malfoy and also the lead singer of My Chemical Romance I think. It absolutely awful and quickly gained a reputation as the worst fanfic ever written, so much so that it became sort of a rite of passage for fanfic writers and readers to go read it and be baffled by it.
