The period refers to the timepoint in which all reality stops and begins to revolve around a woman's vulva. This is a point in time, where holy lambs gallop ferociously while fire attacks their soft, flammable wool. Where unborn fetuses scream and beg comprehensively for another chance and even the most unholy of satanic worshippers lay down to die as fiery planets soar across the sky. Red rivers of fresh, meaty blood , this is where uncreated child dreams commit suicide and serial killers boil their corrupted minds in a large black pot, over intense, searing flames of hate, pain, and aggression.

A bloody horrific mess that descends from the female of the human species once a month, Side effects include extreme bitchiness , violent outbursts , occasional discovery of bloody pads whilst cleaning ones teeth in the morning, an unpleasant fish market smell rising from the females genitals and in extreme cases has led to the male of the species receiving a mouth full of blood during the act of oral sex.
All humans should stay a safe distance from the woman until the period has passed and she returns to her normal level of bitchiness.
My girlfriend was on her Period and forgot to tell me one night , I was rather drunk and so failed to notice the smell of a fish market coming from her lower regions. As a result I obtained a blood squirt to the mouth while attempting to perform oral sex on her which in turn caused me to yell at her , starting a chain reaction that resulted in a violent outburst rendering me in hospital for one week. The week following the period incident I returned home and she had returned to her normal health. Now I stay with my parents once a month as a precaution.
