At the drive-in.....

I am confused about Lesbian Vampire Killers. Are they killers who are lesbian vampires, or do they kill lesbian vampires?

This movie is still in production. Here's the plot...I shit you not:\r A bus full of foreign female students and an army of salacious lesbian vampires. It's gonna be one hell of a night!\r \r Eternal slacker Jimmy Maclaren and his friend, Fletch, are enjoying a walking holiday on The Moors. Thanks to an unfortunate series of events, they find themselves stuck in a remote cottage with a camper-van full of sexy foreign student girls, besieged by a hungry army of lascivious lesbian vampires. \r The slackers are the vampire killers\r
