A rating of how many points someone has scored when Gibbing.
The formula progressively rewards later gibbings more than earlier gibbings.

Gibb Score = Sumation from (C=0 -> Cmax) of {1 - (e / 2)^(Fc - 3)}

Where each C corresponds to a friend circle. And Fc is the number of friends that have been hooked up with in that circle.
A girl who has hooked up with 5 Tke's and 8 Beta's would have a Gibb Score of:

1-1.359^2 = .846
+1-1.359^5 = 4.635
= 5.481 = 5.481
