Manstruation

(noun) man-stroo-ay-shun A period of time when a male bleeds from his anus due to excessive wiping. Due to the continuous need to wipe and resulting inability of the anus to heal, the bleeding usually persists for about a week. After a month or so, the male will forget the effects of over-wiping and assault his anus again to ensure cleanliness after a particularly wicked bowel movement which will initiate Manstruation again.

Due to the similar lengths of time/occurrence between this process and female menstruation, as well as the resultant mood swings and general "bitchiness" males display when bleeding from their ass that also accompany females bleeding from their vaginas, this is known as "Manstruation".

(verb) Manstruate
(continuous) Manstruating

"The running back's manstruation was affecting the effectiveness of his play because he was running like he just rode a horse for ten days straight, and felt like it too."

I saw that dad do the manty shake around 1am at the bar last night! He's a sick dancer, but a horrible father.
