Sequel to douchebag and a more severe insult, originating in the misspelling of the original on comment boards across the internet because the commenter was too pissed off to get it right or to care that it was wrong. Metaphorically refers to a sac of turds, with douce deriving from "I have to go #2" or "I gotta drop a deuce."
I hate that guy. What a doucebag!
