Well first of all, we don't know any history between you two other than you won a 150$ pot off this guy. Now my question is why in the world do you raise to 12$ with AQ especially heads up, I mean do you want the guy to fold and you get no action? (On a side note, I don't know any history between you two and if that was just an intentional move)
As for your question, its possible this guy is thinking you are "bullying" him and is pushing with any two live cards, personally yea I would call since I know there aren't many
hands that got me dominated and I also know I can handle getting sucked out on, not tilt afterwards and still play my game.
So things to consider before you call, are you willing to risk this much on one hand? do you have this guy figure out where you can outplay him postflop? do you think he will stay if you fold this hand or he will leave? I mean to some of those questions there is no definite answer but that's what I would be thinking personally.
