MBS: short for Man-Bitch Syndrome
When a man shows symptoms of PMS, such as:
Man: "I'm having a bad hair day!"
-or-
Man: "Just, you know, let me have some time alone. I just need some me time. I need to think."
-or-
Man: "You're always so mean! You just don't understand! I hate my life!"
-All signs of MBS. If occurs frequently, he may have chronic MBS.
