Erection Ratio 

<e-RECK-shun RAY-shee-OH>

This is a definitive measurement of a man's penis growth potential, or PGP. In the slang world there are two types of penises--growers and showers. Growers are men with penises that are comparably small when not erected, but grow significantly when aroused. Showers are men with penises that are long when not erected, but do not gain very much length when aroused, giving them the appearance of "showing off" when not in use. The Erection Ratio comes into use here. Whereas before there was two types of penises that were loosely defined, we now have a way of roughly determining whether or not someone is a grower or a shower. The Erection Ratio is the ratio of the erect penis to the inerect penis, expressed like 4:1 or 2.5:1. A grower is someone whose ratio is 1.7:1 or higher; a shower is someone with a ratio less than 1.7:1 (but not less than 1:1 or your penis shrinks when you get an erection!).

What is my erection ratio? 35:1. Or in other words, my penis is 35 times longer when erect than when inerect. That makes me a hardcore grower.

Kill Death Ratio 

The Kill Death Ratio, Commonly Referred to as K/D, KDR or Kill/Death, is the average rate of the amounts of deaths you need per kill. For instance, a KDR of 1 means that your number of death equals the number of kills you have. If your KDR is lower than one, then you have more deaths than kills, and vice versa.

Summary (may require some mathematical understanding):
If 0 < k < 1, or log(k) < 0, then you are a n00b.
If k > 1, or log(k) > 0, then you are a good player.
(k is your Kill Death Ratio)

BTS Ratio 

Boob to Stomach ratio. This has to do with the proportion of the boobs sticking out farther than the stomach. Standards are dependent on preferences, but any ratio that has B bigger than S is good.

Alan- I like a 3:1, thats probably perfect for me, but I'd date a 4:2 or maybe a 3:2
Bret- last night you took home a 6:4
Alan- yeah. I double the BTS Ratio when I've been drinking

ass to breast ratio 

The ass to breast ratio is the ratio of where the ass and breasts on a female are in proportion to each other

It is calculated by how much the breasts protrude from the breast bone, and for the ass, how much it protrudes from just above the tail bone.

For example;

A girls breasts protrudes from her breast bone by 4 inches and the ass protrudes from the tailbone 4 inches, the ratio is perfect for that girl

Ratio=4:4

Or you can calculate it by looking at a girl sideways and if the ass pocks out as much as the breasts you have got a girl with the perfect ratio

The ratio can differ slightly

For example;

A girls breasts protrude 4 inches and the ass 3 to 3.5 inches thats ok

Ratio=4:3 or 4:3.5

NOTE
All measurements must be taken from the peak of the breast or ass, in other words the measurement from the furthest point away from the breast or tailbone on the female

good ass to breast ratios are;

5:5

5:4

4:4.5

bad ratios are;

5:1= ok boobs but no ass

0.5:5 = small breasts to the size of ass

4:0= run away, ok boobs but absolutely no ass
