when you have a bro who is also a total douchebag. Basically your stereotypical fratboy Big and with muscles and wears really tight polo shirts with popped collars and way too much cologne. Looks down on other people who are not his fellow bros and thinks he is God's gift to the universe. Most likely has has some form of venereal disease at some point, and will tell girls whatever they want to hear to get them to sleep with them.
hey man, Stacey must not have very good BrONAR cuz that dude she is with is such a douchebro...he's only telling her what she wants to hear so he can get to sharpen her with his pork sword. She thinks he's sincere but he's only interested in the hump'n'dump.
1.a friend, or someone being given the benefit of the doubt on otherwise being a decent human being, who is currently acting as if they were a douche bag.
2. the asshole that you still hang out with, but you're never sure why.
1. Man, I can usually get a long with (insert name here), and I know you and him are tight and all, but the shitting on my couch after drinking all my vodka last night - on a scale from one to douchebro he's a solid douchebro.
