fat factor 

Experts are still undecided on the meaning of this word, but have narrowed it down to two possible definitions:

1. Synonym for weight
2. A scale from 1 to 10 rating how fat a person is; 1 being Mary Kate Olsen and 10 being Sally Struthers

1. I want to lower my fat factor. Its like 357.

2. Shit! That guy must have a fat factor of 15!
