Or maybe the word for a remark with that underlying sentiment/intention.
I'm not sure if I can properly describe the concept. But imagine a situation where you feel spite or jealous towards a person but don't want to admit or others know about it. So you're inclined to do/say something negative against the person you feel jealous or spiteful towards. You would use a remark to somehow humiliate him despite his apparent merit but you say that in a perhaps conceited way pretending that you don't even recognize the person's merit or whatever has caused you to resent him! Wow! I think I couldn't have explained my purpose any longer!
