Pre man-strual syndrome

When a man has symptoms similar to when a woman PMSes.

Like, getting mad/annoyed at simple things and taking it out on you.

John: YOU LEFT THE FUCKING MILK OUT!!! WHAT THE FUCK??? I MEAN I WORK SO HARD *Cries*

Meagan: Uh... What's up with John?

Steve: He's got pre man-strual syndrome.
