When a man makes a woman angry for any reason. This will cause the woman to gain the mansanity. Common causes for the mansanity are when men don't call/text when they should, when a man doesn't clean up after himself, when a man is late for a meeting/cancels last minute.
John hasn't called me in three days! I have the mansanity sooooo badly!

Joe didn't put the laundry on like I asked, I have all the mansanity right now!
