A 1 plus 1 is a particularly easy girl. Can also be referred to as 'the village bicycle'.

Let's face it, there really isn't anything easier than 1+1 now is there?

A rule for gauging a girl's level of hotness when dancing on them in the club when you are intoxicated.

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?!
- Dude I was dancing with this shawty last night, she was a easily an 8!

--Chris, how drunk were you?

-Really spaced dude!

-- Better use the divide by 2 plus 1 rule then.

- Damn, she was only a 5 :(
