'Femme Fatale'

Definiton
A femme fatale (plural: femmes fatales) is a stock character in European drama and a stereotype, usually of a villainous woman, who misleads and ensnares the hapless hero or other males in order to achieve some end they would not freely help her achieve.

The phrase is French for "deadly woman", or "fatal woman." The femme fatale tries to achieve her hidden purpose by using her feminine wiles (beauty, charm, sexual skill); hence she is typically portrayed as exceptionally well-endowed with these qualities; however, in some situations lying or coercion are just as effective.
