Irritable Male Syndrome (IMS) is the male equivalent of the female hormone change during menstruation. Believe it or not but men's hormones change every month too, this results in mood swings similar to those women experience. Luckily it doesn't cause men to bleed through their pecker.
Michael is suffering from Irritable Male Syndrome a.k.a his man period.
