Wow, that's a great question, and HAPPY BIRTHDAY, by the way!  
Before you gals start the party, please agree that you WON'T take photos of anything, because there is just too much embarrassing stuff on the internet, and you don't want to BE that person, so don't even be a possibility.

1. wear your bra on the outside of your shirt
2. paint your nails a horrible color.   fingers or toes
3. do some bad makeup, if you are already wearing makeup
4. call a favorite boy and tell him "I love you".
5. call a favorite boy and ask him to go to a movie with all of you.
6. eat and onion (get those small white ones) or a clove of garlic
7. enjoy a spoonful of cat or dog food
8. obviously, I'm no good at this.  hope someone else comes through for ya.
