Law of Diminishing Marginal Fucks Given

The rate at which one gives gives fewer fucks.

DMFG: G(F)={(D/S)*D{Nbar^2} -- the number of given fucks is equal to the days left in the semester times the distance from you to the nearest bar (Cornell notation replaces Nbar with NBrB)

There's an economic principle at play here. One that I think a lot of people take away from econ courses. It's called the Law of Diminishing Marginal Fucks Given (or DMFG).
