There are 2 ways to rate a girl’s appearance:
The “Would You” Scale and the 1-10 Scale.
The “Would You” Scale is simply what it says. Is the girl bangable or not and “Would You” do her. This scale is good and all, but doesn’t describe the degree of bangability like the 1-10 scale.
We calibrate the 1-10 scale by starting with a 4. Anything on the range of a 3 and below is considered a “Monster” and you need to drink alcohol to get aroused for sex. If a “Monster” is all you can get, you better pull a “Black Op” and never admit you did such a horrific act. However, every man has banged a monster in his life because men are unable to resist free, no investment sex.
This is called a “Black Op”. A 4 is a chick you don’t tell anyone you did stuff with. She is most likely Busted and needs plastic surgery. It’s a secret mission that is never discussed for the sake of your dignity.
A 5 is slightly unattractive. This is someone you wouldn’t look at twice. However, she is do-able and you wouldn’t be embarrassed to tell your friends.
A 6 is a girl who is cute when she works at it, but her flaws are easier to notice. This is someone you wouldn’t be ashamed of. Could be date material/maybe more. Still, it’s a respectable rating.
A 7 describes the Girl-Next-Door cuteness. She has no major flaws and is girlfriend material. The problem with 7′s is that while you’re out with one, you typically run into a handful of girls who are better looking than her. Most men will start having thoughts of “Can I do better?” However, this is typically who you would marry.
An 8 is “Hot”. The hotter a girl is, the less she has had to work on her personality to be liked by others. Because her looks have been enough to get her what she’s wanted throughout her entire life, she doesn’t have the training or desire to go the extra mile to please and engage you.
A 9 is what you would describe as “Super Hot.” Getting a 9 seems to be more luck and timing than skill because —besides celebrities— there is no man who consistently gets them. The personality problem you had with an 8 is multiplied with a 9 in logarithmic fashion.
The only difference between a 9 and 10 is makeup, clothing, lighting, and most importantly: PHOTOSHOP. So therefore, 10′s do not exist naturally in the wild. Describing a girl as a 10, or dime piece, is unreasonable since you are admitting that the girl is perfect, something that no human is.
