If you ever meet a girl drunk and you can't remember if she was hot, look at her Facebook. Most guys tend to look at the ones where she is all dressed up at a bar or club. Don't do that, it's misleading. Look at her family photos. Those are the ones where girls don't usually wear as much makeup, if any at all. Preferably the ones that say, "just hanging with mom...cooking."
Any girl can look hot in a club with the right lighting, you need to check out the pictures when she's in sweats, on her cycle, with bags under her eyes.
