Measure of how sexually attractive a woman is on a scale of 1 to 10. This scale is purely lust driven, so cuteness, social status and personality don't count as much as how tempting and sexually desirable she is to the eye of the beholder.
Steve: Check out that girl at 10 o'clock!
Tony: She is alright. I'd give her a 5 on the bootyscale.
Steve: What a superficial snob! Look how classy she is... does that not count?
Tony: Sorry, not hot enough. Still a modest 5 though!
