n. General Female Population Hotness scale.
A number used to sum up the average hotness level of all the girls at a particular school. A score of 10 means that 10 out of every 10 girls will be hot. A score of 0 would likewise mean that 0 out of every 10 girls will be hot. This number can be decided by gathering a group of friends together, looking in a school's yearbook at all the girls in the same grade as the group and older, and rating each girl from 0 to 10. One must record all ratings down on a sheet of paper, and then find the mean of the group of numbers. The resulting number will be the GFPH factor.
"My school's GFPH factor is about a 2... I wanna transfer to Dunham."
