A combination of the terms douche bag and dude bro, which describes an even more annoying type of person than each term used singularly.
This type of person was/is probably in a fraternity. They may hold an esteemed position at a company. He is a pompous asshole. However, he is also fun. He likely surfs, shotguns beers, and smokes weed. He probably spits on the sidewalk and talks too loud to his clients/friends on his cell phone in a quiet place like post office or elevator.
My coworker, Zac, just tried to high five me after yelling at our waitress for forgetting his side of fries that he never even ordered. That guy is such a douche bro.
