[doppelganger]

I wanted to clarify the use of douchebag, as I believe that the word "douche" means shower in french.

In America douche is something that women use to clean their "lady parts" when they are smelling "not so fresh and clean." The apparatus used to insert this liquid is called a douchebag, and thus calling someone a douchebag is intended to be degrading and offensive.
