Slutonomics 

The study of the cost of having a slut, or sluts, in a person's life and in society as general. In microslutology, the personal expenses of having a slut girlfriend, friend with benefit (FWB), wife, or prostitute are considered, but macroslutology examines how sluts contribute or deteriorate an economy.

This is a substudy of slutology.

Wow, I've learned so much in slutonomics 101 today! Although having some random sorority slut suck my cock can feel great, the cost of getting an STD test is much greater!
