When a man has a nose bleed. This may or may not happen every month on the man-period mensterul cycle.

Man Period is when the boyfriend decides he wants to be a girl and starts acting like he is entitled to be a whiny little bitch. As women, we have to accept the Man Period for what it is. A period without tampons, pads, or blood.
I just want to be up in the mountains, away from everyone so I can get through this awful Man Period that it currently bleeding out of my metaphorical Mangina.
