Unbearable
Unbearable is a comedy fanfic by Smileyfax, which due to extremely bawdy humour should be considered an 'R-rated' fic.
The description on the fanfic is "Daria is chased by a menacing figure from her past", which is true but the apparent thriller aspect rapidly becomes an increasingly absurdist comedy, involving Daria and Jane, Daria's ex-boyfriend, Jordana, and the BATF federal agency as depicted in Beavis and Butt-head Do America.
