(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

Something that happens every other day, and is NOT the same as menstruation. It is when a man becomes irritable, experiences cramps and bleeds from his willy. As shops do not stock male sanitary products, the man often resorts to using tissues or bits of scrap cloth to absorb the bleeding. Unlike menstruation, manstruation happens every other day and only lasts around 10 hours.
"Woah Mike are you experiencing manstruation? Don't worry I've got some toilet paper in here somewhere."
