cherchez la femme

A French phrase meaning "look for the woman," the idea being that when a man starts behaving strangely, it is often because he is attracted to or involved with a woman. The phrase is typically attributed to French author Alexandre Dumas. A: "Todd has started dressing better and acting much more mature lately." B: "Hmm, cherchez la femme, methinks."

This French phrase that translates as “look for a woman,” originated with the elder Alexandre Dumas in his novel The Mohicans of Paris. Its meaning is that unusual male behavior can often be traced to involvement with a female. For example, countless generations of adolescent boys who never paid attention to their wardrobe or personal grooming suddenly became interested in clothing fashions. They washed their face and combed their hair without being told to, and spent hours chatting on the telephone (now a computer or handheld device) with the classic teenage boy's dreamy/dopey look on their face. Their parents would regard the phenomenon with a knowing and bemused expression as they told each other, “cherchez la femme.”
