"Cupcakes"

Cupcakes is a dark fan fiction set in the My Little Pony: Friendship Is Magicuniverse. It depicts the character Pinkie Pie as a serial killer (though still keeping her in-universe bright and cheery demeanor) who drugs her friend Rainbow Dash, drags her to a hidden cellar and proceeds to slowly and brutally mutilate her to death. The extremely graphic nature of this fic has made it rather infamous within the MLP fandom.
The "Cupcakes" fan fiction is thought to have first appeared on 4chan's imageboard /co/ sometime in January 2011, though the date of original post remains unknown. A canonical reference to the Episode 12 in the fan fiction suggests that the earliest possible date of post is January 7, 2011. On the Equestria Daily version, the authorship has been attributed to "Sergeant Sprinkles". The earliest archived instance of My Little Pony fan fiction is "Junior Speedsters Forever" posted via Equestria Daily on January 24, 2011.
Though many stories on Equestria Daily are labeled as "Grimdark" (a slang term for a dark and/or violent fan fiction), it is the only story with the label "GRIMDARK AS FUCK".
