MANSTUPID: When a man is being completely oblivious to the fact that he is doing something hurtful and/or insensitive to his significant other. He is not thinking how it would make HIM feel if the same thing were done to him in reverse. He has no idea that he should give his significant other the same respect that he would surely expect for himself by correcting the situation and acknowledging the painfully obvious double standard.

Joe has been secretly communicating with his ex the entire time he has been with his new girlfriend and is being so incredibly manstupid by not realizing this is wrong and hurtful.
