I was browsing through the genre's list on goodreads, when i found a genre called "Bizzaro fiction" a sub genre of horror i think. "Bizzaro" yeah you've guessed it right : weird shit!
"Bizarro fiction is a contemporary literary genre, which often utilizes elements of absurdism, satire, and the grotesque, along with pop-surrealism and genre fiction staples, in order to create subversive works that are as weird and entertaining as possible".
Great odds that's it's about crazy people doing crazy ,disgusting,scary-crazy-disgusting things. Of course this is mere speculation on my part from the many titles I've seen on goodreads.
-A Bear is Eating Me
- A Haunted Vagina
-The Menstruating Mall
-Satan Burger (followed by the cover, of a naked guy crouching over a plate he's I assume about to SHIT on)
- The Baby Jesus Butt Plug
-Ass Goblins of Auschwitz
-Sausagey Santa ?
