BENNETT: I invented a some new slang today. Female douche bags are now known as "douche baguettes" Eh? Eh? Eh?

I think it works in so many contexts, too. "Hey, check out that baguette wearing hot pants and Uggs in the snow" or "the baguette dropped her phone in the toilet" or "the baguette just called our black waiter, "son".
I feel that douchebagery is a universal institution exhibited by both men and women. By overlooking women as possible douchebags, we are overlooking half of the possible douchebag candidates.
