The Weingarten Ratio is a ratio used to rate girls. It is a step up from the normal 1-10 scale.
You take the girls hottness (1-10) and divide it by her self esteeem (1-10). You want the resulting number to be as large as possible. Using decimals will give a more accurate number.
Named after Weingarten, the theory is that you want a hot girl who either doesn't realize her value, or is dumb enough to spread her legs for you. A hot girl with high self esteem wont put out, so she's not worth it.
Joe: Dude, I totally met this hot 9
Phil: What's her self esteem?
Joe: Like a 7
Phil: Thats only a 1.3 on the Weingarten Ratio. Not worth it.
Don Juan: Hey, I just beat my Stroke Nut Ration (SNR) record of 35....I got to 36. I would've gotten higher, but I thought of a guy's '
dick/asshole...It sucks; I got jizz all over my courderoy.

Ron Jeremy: No! I will fuck them all!
Peter North: There's only one way to settle this! Cockfight!!!
The bang ratio is the percentage of people who "like" a post on social media that the poster would potentially like to bang. For example, if someone uploads a picture to facebook that receives 20 likes, 8 of which come from people that the poster would enjoy having sexual relations with, the picture has a bang ratio of 40%.
Because the general purpose of most men's lives is to have sex with as many people as possible, (and because they have an unstated sexual attraction towards a large number of their female friends) most men are constantly attempting to post things that will generate a maximal bang ratio.
Dude 1: "I can't believe you uploaded a picture to Facebook of you frolicking in a meadow with puppies and baby horses."
Dude 2: "Dude, girls love pictures like that. That picture has 55 likes, with a bang ratio of 85%!"
