Learned and adopted by males at an early age, the universal female rating system is widely accepted by most modern cultures. The system is used by rating either a females personality, or more popularly used, physical attributes, on a scale of 1 to 10. One signifying a total ugly, fat, un-doable dog-faced whore, to a 10 being a beautiful, perfectly proportioned gift from god.
The Universal Female Rating System is widely accepted anytime during conversation, especially when difficulty is found trying to explain a woman you saw- anywhere.
Example of the Universal Female Rating System
Joe: "Dude, our waitress is a 9."
Kyle: "Are you kidding? She has a lazy eye! She's a 6 at best."
Joe: "Yeah, but her ass is a 10, and its not the face you fuck, it's the fuck you face."
