A measure of the number of Dufi currently on the road with you.

On a freeway, the Dufi Index is defined as 100 minus your current average speed. The higher the number, the slower you go.
Man! The Dufi Index is high today! Traffic is congested because of the large number of dufi on the road.

A variation of the heat index for weather. The fatman index measures how well each person handles the heat. Some people don't mind the heat, others fear it like grim death. The worse you handle heat, the higher the fatman index. This is based on the real lazy fat man who hates the heat and sweats like a pig. Originates from the area of Genoa, Illinois.
"This heat is terrible! fatman index is through the roof!"

"Better not go outside. It's hot and humid, not to mention the fatman index."

The numerical value given to how Stabby one is feeling at a particular moment. Ranges would exist on a 1-200 range with 100, of course, being average.
My dog is depressed, my girlfriend broke up with me, my parents bought a screechy bird which keeps me up all night and my job demands I walk on water to be an average employee!! My Stabby index = 175 right now!

the criteria that dictates whether or not a girl is scroggable (fuckable).
I guess it's all in the eye of the beholder.
That chick in the mall with the inch and a half nipples punching holes through her blouse and buns of steel definitely ranks the highest on my scroggability index.
