An excessive indulgence in douchebaggery whereby multiple douchebags or douchebottles gather and openly celebrate their love for hairgel, spray tanning, puckering their lips and throwing gang signs in candid photos, and the other nonsensical actions typifying the douche culture.
"Would you look at the douchebauchery going on in this club. I can't drink here...let's move on."
Engaging in particularly heinous acts of rowdiness, drunkenness, and savagery. Often, if not always, with a particular disrespect for the female gender (a grammatical blend of douchebaggery and debauchery... obvi).
Bro, there was some epic douchebauchery taking place at the "open party" last night.
Yeah, I can't believe that broad period-ed all over the president's sheets after I banged her.
