noodle ratio 

This is the ratio of how many times you can sex a girl before your penis becomes like a wet noodle.

If you can sex a girl like 3 times within 3 hours and then your penis becomes a wet noodle, your noodle ratio is 3:1.

Oh man, my noodle ratio has gone up since last year, now I got a 10:1 noodle ratio!

L/F Ratio 

The L/F Ratio or Likes/Friends Ratio is designed to measure what percentage of your Facebook friends like your profile picture.

It is obtained by dividing your profile picture's likes by the number of friends you added, times 100%.
For example: 50 likes, 300 friends -> 50/300 x 100 = 16.7
The L/F ratio is a really handy tool when you want to figure out how many of your Facebook 'friends' are really interested in you! Also, it enables you to compare your ratio to your friends'.

A typical L/F ratio lies somewhere between 3 and 20

Wow she has a really high L/F ratio! No wonder with a picture like that!

The Ratio

"The Ratio" is a fundamental rule of life, relating to the direct correlation between the attractivenes and assholiness of a male. With "The Ratio," degrees of attractiveness = degrees of assholiness. Men who are uglier must act nicer to attract a mate and men who are more attractive already attract them, so they act like assholes. Exceptions to "The Ratio" include men who perceive themselves to be more attractive than they actually are (these individuals usually fail to get a mate). Other exceptions include males with distorted self-images who consider themselves less attractive than they actually are, so they display kindness as well (these usually are very desirable as mates).

Man I really hate The Ratio.
