3.
A woman that is generally known for lying and taking advantage of men. The origin of this specific definition comes from an old wives' tale about a young woman who is persecuted and inevitably beaten for her promiscuous behavior in the early 16th century, after sleeping with a group of men and giving them an illness without any known cure at the time.
