I hate the fact that everything is "sluttifferic" in college. I'm going to school outside of Niagara Falls, and it's colder than hell right now - I can't imagine how cold it will be on Halloween night. And it's not appropriate for the females on campus to wear something that's not slutty - I went out last year dressed as a Duracell battery, and got so many evil eyes from drunken bastards.
This year I'm going as Pyramid Head - it would be a crossplay and fun to watch guys and girls reactions to PH. I usually don't do scary - most of my costumes aren't off the shelves - most have a handmade component to them.
Anyhow, just my rant towards the fact that most girls on campus decide that it's ok to wear a miniskirt and freeze to death on Halloween.
