The FAT scale is the single most important measure when judging women. Each letter represents an element of a girls features F for Face, A for ass, and T for Tits. Each letter is then assigned a number from 1-10, depending on how hot she is. 1 is disgusting, 5 is average, 10 is unreal. State their score in respective order. For example, a pretty girl with an average ass and big tits might yield the score 7, 5, 8.

Guy 1: 8, 10, 9!
Guy 2: I hope you rode that ass like a Mexican!
