A variation of a douche in which only harsh, direct, truthful facts are stated that are blasted out of proportion for no apparent reason with the goal of ruining someone's day, and personal outlook. This is someone who thinks they are being a douche, but is just a full blown, direct, cynical piece of shit dick head.
Holy Hell, that kid is trying to be such a douche, but he is just being a no good, opportunist, cynical trouche with no apparent motive other than being a posing son of a bitch.
