Ideas for things to do for my halloween get-together (16-18 year olds)?

I thought we could get dressed up nd watch horror films. Nd for food i thought we could get a chinese, because i thought it would be funny walkin along to the take-away dressed up. Nd i'm gunna get a few cheap decorations, like banners nd hanging skeletons. Any other ideas, i was thinkin about doin a chocolate fondue, with strawberries nd marshmallows, what do you think? Thanks
