The first six months of a woman's engagement, when her number one priority is informing as many people as possible that she's engaged and/or showing off her wedding ring as much as possible.
It's difficult to get anything done in the office while Suzy is still in the Braggadocio Stage. All she does is talk about the wedding.
Cook: "Who's that loud fuck sitting across the bar."
Pete: "Oh, that's Adam."
Cook: "What a dickhead."
Pete: "Yeah, but in spite of all the braggadocio, I actually like the guy."
Cook: "Really?"
Pete: "No, really?"
A braggadouche is a person who, through gratuitous and excessive bragging, becomes a douche-bag. "Braggadocio" came from the word "braggadocio" plus "douche-bag". Hence braggadouche.
Mark: Hey look its Gabriel again, all he ever talks about is his lawyer job, downtown condo and new mercedes.
