slut

(highly derogatory): A woman with the reputation of being promiscuous or indiscriminate in her choice of sexual partners. In some cases this reputation is accurate, in which case the woman in question has earned the reputation by engaging in sexual activities so frequently or commonly that her habits have become widely known to the public. When it is a reputation generally, the term is normally quite accurate. In other instances, the label may be inaccurate and merely used to slander a woman for an isolated case of sexual indiscretion, or it may be a prejudice against a scantily-clad woman. It may also be used by other women in gossip or confrontation, in which case its use reflects extreme bitchiness. In any case the term carries negative connotations and is normally used in the pejorative; nevertheless, there exist males whose next action upon labelling a woman "slut" is to proceed to have sex with her.
