1 - 3 = ugly, your eyes hurt looking at them
4 = below average, maybe losing some pounds or a new haircut would help
5 = average, not ugly but not good looking either
6 = decent but nothing special, maybe just somebody you bang once or twice
7 = very attractive, you'd date and screw them but the party doesn't stop when they walk into the room
8 = very hot, can't leave the house without some dude hitting on her, never "lonely"
9 = almost perfect, should make money off her looks
10 = perfect, flawless, ideal etc
