A number used to measure how sexually attractive a girl is by comparing her
butt to her waist. This also shows how big a girl's
butt truly is.
This is obtained by measuring the smallest part around a girl's waist and subtracting that from the largest part measured around a girls
butt and thighs.
The following A/W Ratios are in inches
>0: Waist is bigger than
butt, she must be flat and fat which won't look good at all. Fortunately this is rare (>5%)
1-5: Her
butt is ok, this might not look good everyday and probably won't grab your attention. This is quite common
(75%)
6-9: Her
butt is pretty big, this is very noticeable and probably will grab your attention. This is quite uncommon
(15%)
10+: Her
butt is amazing, this looks unreal and might make you stare for a bit. This is also known as an extreme ass. This is extremely rare, and you
may not see another one like this for months.
(>5%)
The distribution of the different A/W Ratios depends on booty geography
