A word derived from a proper name and a familiar word; douchebag and Frankenstein. The combination of these two words suggests a douchebag (see def.) and something completely mutated personified. The combination of the two is defined as such:
1. someone who has taken the act of being a douchebag to extremes never seen before, making the concept ofdoucheness "come alive".
"I'd really like to go home right now, because this is extremely boring, but my boss is being a total douchebagenstein."
The epitome of a douche. You know those people who are generally so retarded that you just want to have a 1000 pound hand so you can crush their face over and over again.
