A writer of limited talent who weaves a myriad of complex plot lines into the beginning of his work, only to later abandon most of those plot lines in a lazy ‘deus ex machina’ story ending.
Did you watch the ending of ‘Battlestar Galactica’? There was a really doucheex machinist at work on that final episode!
The guy who enters the room while you're watching a movie and then ruins the ending.
Based off of the Greek dues ex machina meaning the "God of the machine" that would enter the play near the end and solve all of the problems the characters would have.
Guy 1: Hey you watching a movie?
Guy 2: Yeah, it's The Sixth sense.
Guy 1: Oh, I love how Bruce Willis is dead at the end of this movie!
Guy 2: Thanks douche ex machina
