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.
Friends in your contacts on your phone who only send you forwards, and when you really want to text them, they never text you back (Especially right after a forward.)
Robert: Ooh! A new text from Claire! *opens it* All I get from this chick is forwards! I'm not going to "pass it on" and I'm not going to die..
Jill: Looks like you have some forward friends!.
Robert: There's only one friend...
Jill: I know.
