A common tool used to roughly measure the attractiveness of a woman through 10 general features.
The most commonly judged features, though varying between individuals, are:
Hair, Nose, Teeth, Lips, Neck/Chin, Chest/Breasts, Stomach, Waist, Hips and Rear/Ass.
For each feature on the list, the woman can score a point. If all the features on the list are good on the woman, then she scores 10.
Dude 1: "Dude, did you see that chick I was with last night?"
Dude 2: "Yeah dude, she was totally a 10 *on the 1-10 Female Attractiveness Scale"
*No-one would say that but I need to include the term in the definition
