In my case it is not Douchebagese. But I learned it by studying douchebags at an Ivy League School plus watching lots of movies about completely irredeemable s, videos in Douchebag in the internet (where they infest Youtube), reading many articles in Douchebagese. I even got to interact with complete and total douchebags in their native language when they told me to mind my own ing business as they smacked their sobbing wives around on a public subway car in front of everyone, spilling their coffee, making a mess and an awkward scene leaving everyone else feeling extremely uncomfortable.
