Every year, Nerdcore releases a special calendar paying tribute to pop culture with sexy pinup girls. The 2010 Calendar, currently available for pre-order, is a bloody, beautiful homage to horror flicks, and it's a perfectly timed Halloween gift for any discerning masturbator of the macabre friend you may have. According to Nerdcore, "no genre has been more synonymous with nerds and nudity than horror," and we couldn't agree more. Their 4th annual calendar features cover model Jana Jordan getting paranormal with a TV set, sultry scream queen Justine Joli in the most vintage of psychotic shower scenes, Bobbi Starr sewn together (literally) in a more naked version of Frankenstein, as well as Aria Giovanni, Kayla Jane Danger, Karlie Montana, Mosh, and Zoli Suicide getting their scream on. Check out some of the hot, nearly NSFW photos after the jump. Can you guess all the horror movies to which the photos pay tribute? Does it really even matter?
