A combination of "polite" and "poseur," a Polseur is a person who acts overly nice to others when they do not really mean it. The worst type of Polseur is a woman who acts too nice to a man, thus leading him on.
After Joe was rejected by Mary, he realized she was nothing more than a Polseur for exuding artificial niceness to him.
