slasher fucker
The word "slasher fucker" is a term formed by a surprisingly large audience of horny teenage girls on Tumblr that claim that they want to have sex with a slasher. (slashers are fictional serial killers who take the role of an antagonist in most horror movies. Michael Myers, Jason Voorhees, and Freddy Krueger are some fine examples of popular slashers in the film industry)
"I would totally fuck Jason Voorhees, and I don't care what anyone has to say about it. LOL, I am such a slasher fucker."
