So there's this guy I know. And sometimes he acts in a particular way that I hope there is a word for (or at least a phrase). Let me describe:
Situation: Dog bares teeth at his girlfriend, which is obviously a problem, but this dog would never bite, it's just his way of saying fuck off at the moment. (every attempt is being made to lessen this behavior)
His response is: Discipline the dog, which is fine. But then, 24 hours after the fact (when the dog has completely forgotten the event) and without seeing the dog since the event, continues to say things like "Bad Dog" and make the dog feel shameful, even though it has no idea why. This is obviously not good training (any trainer would agree). When asked what the dog did he says:
"I'm still mad from last night. The dog needs to be disciplined." And even with a discussion about the dog not possibly remembering the offense, he persists in a smug know-it-all kind of way. As if "I have all the answers, even though I have no experience in this, and the way it's being done is complete bulls***. So what I'm going to do is, without any consistency or discussion (and even though it's not my dog), implement this action as I see fit"
So that's just one scenario, but there are several others. I'm less worried about the behavior of my friend (he knows about it and apologizes when he gets like that), but would like a concise way to describe it when it occurs.
I feel like it kinda falls somewhere around "smug know-it-all", but that isn't quite it. The smug part is correct, but the know-it-all is rather more like an idea formulated once by the party of concern then believed as gospel afterwards (they'll defend it to the death, though a second before it wasn't even a thought)
