orcishgamer: Don't know, but I might suggest a movie, April Fool's Day,

Wishbone: That's a great movie. A little dated, but very good.
On the subject of horror movie drinking game rules, drink whenever:
1. A mysterious shadow moves across the background.
2. A character backs away from safety into danger.
3. A girl walks around in her underwear for no apparent reason.
4. Anyone has sex.
5. Someone goes alone to check what that noise/light/shadow was.
A few more:
6. When a scene builds up suspence for the monster/villain to leap out of the shadows.
7. When the token minority is killed.
8. When the monster/villain has some kind of nonsensical weakness that leads it his/her/its downfall (e.g. Water, light, milk, the power of love, you get the idea).
9. When the monster/villain isn't quite defeated, so as to leave room for a sequel.
10. When the lead female character acts like a useless moron.
