The Fairusa Scale is the scale is used to determine that a woman of unknown hotness, is either actually really hot, or that you want to punch her right in the mouth.
The scale takes into consideration all possible possible images of Fairusa Balk, then you pass in the woman of unknown hotness, using specific comparison algorithms, comparison operators, and levers and pulleys. you can then extrapolate that you may in fact have to punch a woman right in the mouth.
this scale actually runs along side the normal Scale of Hotness that is also know as the 1 - 10 Scale of Hotness.
Damn, look at that girl over there, I cannot tell if she is hot or I just want to punch her in the mouth, I am going to need to run this through the Fairusa Scale to find out.
*BAM* right in the mouth, she was a 2,
