In a slasher, the rules for survival are pretty simple:
1. Be a woman (I'm boned)
2. Be a virgin (...shut up.)
3. Be of a chaste temperament (I masturbate. Am I boned?)
4. Wear tasteful clothing (doesn't work if there aren't sluts in the cast)
5. Do not smoke (Yay, I pass!)
6. Do not partake in recreational drugs, not even once (Probably boned?)
7. Do not drink (So boned)
8. Have some murky connection to the slasher OR Uncover the slasher's backstory before he kills you (I'm good at research, so I'd probably make that one)
So my average is 3 out of 8.
Yeah, I'm majorly fucked.
Follow these rules, or twist your life around to meet these requirements, and you will survive the likes of Freddy Krueger, Jason Voorhees, Michael Myers, Leatherface, Chucky, Pinhead and the Leprechaun combined.
