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 of doucheness "come alive".
"I'd really like to go home right now, because this is extremely boring, but my boss is being a total douchebagenstein."
