When a woman performs a sexual act and after (or during) said act calculates the relative worth of act. Often, this is followed by demands for remuneration from the recipient of act.
Damn, Tiffany gave me the hottest blowjob last night... then she ruined it by doing whore math and making me take her out to dinner afterward instead of just going to sleep.
