A very accurate and new measurement scale used to measure the hotness/attractiveness of a man or woman. It's an acronym: F stands for Face, A stands for Aura (personality, how they carry themselves, etc), B stands for Body (figure, boobs, rump, etc.). Each letter is given a number out of 10, ending either with a number out of thirty or something like this: 7F-5A-9B.
Boy #1: Ok, what about Jennifer Aniston?
Boy #2: On the FAB scale, 8F-9A-7B. If you're referring to the "Friends" era, 9-B.
