I agree, a very very very offensive word. Su Ki was making a distinction above, but here in the U.S., both are the same, whether you use both words or just the first one. Both are extremely offensive.

For once, the Urban Dictionary is quite helpful here. In ascending order of contemptibility we have: jerk a**hole douche bag motherf***er So..not a very nice thing to call someone, then. Not to be confused with 'douche', which is simply brainless.

Hello, douche bag is a very rude word we use to call someone a jerk or a very rude, uneducated person. It is not nice and should definitely not be used around formal and professional friends, people, or events.
