6. The Promiscuous Harlot
For some reason, in the horror universe sex - and under-age sex in particular - is deemed a more repellent thing than murdering teenagers in the name of vengeance or just for the sheer untold joy of it. As a rule of thumb, if you take your top off in a horror film - whether you're male or female - you're bound to be up for the grizzly chop, and if you go further and commit full on sexual acts your death will be even more bloody. Ever since Jason Vorhees decided he didn't like the sexual promiscuity of the Crystal Lake teens, anyone with a libido and a low cut vest has been the fairest of fair game for horror movie killers. If your boyfriend is pressurising you into having sex in a dark, creepy cabin, it's probably not all that safe in the first place - but if you've recently heard a news report about the suspicious death of a local you should definitely consider telling him to take a cold shower and get Jenga out. So, keep it in your pants people, and you might just see the light of day by the end of the film.
