A 1-10 scale typically used by men to rate the attractiveness of a woman based on her physical features such as face, body, boobs, ass etc. with 1 being VERY ugly and 10 being VERY hot. If a woman had an ugly face but a really nice ass or vice versa, she would be considered around a 6. The better the features, the higheron the scale they are.
I've just seen a 7 in McDonalds. Amazing ass and boobs but face uglier than a rat.
Mostly used on 4chan during greentextstories, it can be used to rate how attractive a female is.
An ugly female would be a 1/10, and a hot female would be 9 or 10 out of 10.
