fucking on borrowed fuck
An intense psychological neurosis frequently exhibited by prostitutes. Having got themselves completely fucked over and having traded all intellect for the constant compromise of impressing a different group of Johns every night (stupidity is after all highly varied) they are left with little or nothing of any substance. They use the last groped glimmer of intelligence to imitate other women so as to keep on fucking. Hence, fucking on a borrowed fuck.
That hooker was watching me all night, I think she was taking notes so that she could start fucking on borrowed fuck later.
