Simply begin by judging her hotness out of 10, then divide that number by 2, and add 1.
NOTE: Will not work for girls who you rate less than a 2, but if your drunk and you think they're a 1, why would you dance with them in the first place?!
--Chris, how drunk were you?
-Really spaced dude!
-- Better use the divide by 2 plus 1 rule then.
- Damn, she was only a 5 :(
