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.

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

EF ratio

A man's erect/flaccid ratio. Can be calculated using inches or centimeters, as the ratio will not change.

A penis which is 6 inches while erect and 3 inches while flaccid will result in an EF ratio of 2.
Just cuz your dick is 4 inches while soft as compared to my 2 inch soft dick doesn't mean it's bigger. I have an EF ratio of 4, while yours is 1.5

In/Sent Ratio

The ratio between your received texts (inbox) and Sent texts (outbox). If your outbox has more texts than your inbox than you are probably a loser whose friends don't wanna text you back. If you inbox has more texts than your outbox, you probably have friends and are cool.
