I am glad there was enough of a man inside you after all to apologise although it would have been way better without the link.

I don't know of any book in any language, I don't know any language, come to that, where calling a girl you don't even know a "slut" out of context is an acceptable thing to do. If you are not able to differentiate between acceptable and unacceptable uses of such words, maybe it's best not to use them at all.
