The word 'sl-t' is harsh and not called for, but it means a woman who sleeps around with a men multiple times. Apparently it seems to have been acceptable for some men for centuries to sleep around with multiple women and 'he's a man in every sense of the word', but let a woman sleep around with more than one man and she is a 'sl-t' in the eyes of some men. Fair? No! It is no ones business what the private life is of any woman and often she is far more discreet and less boastful than men that do the same thing. However, a woman that has sex with a group of a men at the same time with no morals is often called a sl-t.
