Who knows, it might help some people avoid being douchebags. I am sure ex #2 loved being called a bag o' douche. I would like to think that most guys are not intentionally trying to be douchebags. I might be wrong, as some people get advice to be an asshole, because that can get men laid by certain types of females.
Actually, Alex, a big part of my definition of "douchebag" is knowlingly and willingly harming or allowing the harm of someone else, when it could easily be stopped/prevented/addressed, because it benefits you- "using," and to another's detriment. So, I wouldn't say it's something that can
really be unintentional. Quite frankly, I'd assume
any guy I'd ever shag would, given enough time, eventually do something stupid and hurtful, but that's part of the human condition. It's the intent (and the amends-making/genuine work toward non-harm) that seperates human error from douchebaggery.
