menstrous 

(adj.) having the ugly or frightening behaviour often attributed to "monsters" manifested by women when experiencing PMS.

The extrinsic-origin of the word is to be found in Slavic languages where "monstrum" stands for "monster", and so a noun of this word (a lady in PMS) would therefore be a "menstrum".

Selena threw her menstrous look at him and in it he could see all the fearful wretchedness of a wild animal captured.

monstrous 

If you describe a situation or event as monstrous, you mean that it is extremely shocking or unfair.
She endured the monstrous behaviour for years.
I just hope the people who committed this monstrous evil will be able to live with themselves.

The nephilim were a monstrous brood begotten of the intercourse of the supernatural beings called " sons of God " with the women of earth.

Mansteris 

A guy you mess around with when you hang out with him for no apparent reasion. You do this even though you know better, it happens almost everytime you hang out. This is how someone becomes a Mansteris. These can be good things or bad things. Mansteris(s) can become very negitive people in your life and an object your friends will use to make fun of. You and your mansteris(s) activities usually take place in random places when you don't think your friends are looking.

(1)Hey Rebecca, there goes your mansteris, boR.
(2)Omg! she made out with her mansteris in the woods at his party!?
