1. The Crying Drunk Girl:

And the crying usually happens out of nowhere. Good luck.

2. The Happy Drunk Girl:

For the first time in awhile, she was truly happy. And then she remembered that she was drunk.

3. The Stripper:

I guess alcohol can make you get really warm or something? Like along the lines of, "it's getting hot in here, so take off all your clothes..."

4. The Designated Driver:

If they're sober, they're driving.

5. The Single Girl:

This one is easily spotted in little to no clothing, flirting with every XY chromosome she sees.

6. The Girl In A Committed Relationship:

This girl hides in corners away from other men while wearing clothing that looks good on her but lets you know she isn't trying to "get some" tonight.

7. The Girl Interested In Your Boyfriend:

Back off. 'Nuff said.

8. The Wine Lover:

The girl in her pajamas is only there for the wine.

9. The Shot Taker:

She'll ask you if she should take another shot. You'll say no. She'll take 3 more, and then ask you what she's taking shots of.

10. The Girl Who Is One Of The Guys:

You'll see her surrounded by guys at a keg stand, not because she's single, but because she's one of them.

Next time you go to a party, figure out which one of these girls you are (or which one you are dating)!
