"In most of the world, 'slut' is a highly offensive term, used to describe a woman whose sexuality is voracious, indiscriminate, and shameful. It’s interesting to note that the analogous word 'stud', used to describe a highly sexual man, is often a term of approval and envy. (...) We have a problem with this."
