Having sex on the grave plot of a departed loved one, similarly to how Mary Shelley fucked her husband on her mother's grave
Guy 1: Hey me and my girl just Mary Shelley'd, It was kinda gross but oddly arousing
Guy 2: Wow, thats dark

Get the Mary Shelley mug.
Author of the widely renouned "Frankenstein", and many other pointless works of literature. Her name can be used to replace coarse insults, or curses.
"Jakes a mother fucker."

replace "mother fucker" with "Mary Shelley"

"Jakes a Mary Shelley."

For extreme situations, place "fucking" in between "Mary" and "Shelley" to recieve a redundant yet firm insult.

"Fuck you, you Mary Fucking Shelley!!"
