look up any word, like hipster:
 
31.
Flawed.

Once a girl reaches puberty, these hormones take over and she starts to have boobs, curves, and becomes more emotional and feminine etc. These hormones also enlarge her hips and uterus. This lining builds up in the uterus and sheds itself every 28 days if she doesn't get knocked up, thus she gets her period.

People tell me, "Well we have periods because we're supposed to have babies!" But even if this were true, I read this study that a woman ovulates 400 eggs in her lifetime. Who could actually have 400 kids? Even in the old days when they had like 12 kids and they only lived to be like 60, a woman would still have more periods and pain than she would kids.

Now it's the 2000s and nobody has 12 kids anymore, some people don't even like or want kids, but we're still stuck with periods and the average age of menarche is declining due to all the calories and stress. As a result, we've suffered too much from periods: we miss school, lose blood, have cramps, waste money buying "feminine hygiene" products, and basically go through a lot more than the guys do.
Periods are flawed.
They were always flawed, even in the ancient days.
Too much blood loss and waste.

1. A period of pure agony for a female, lasting way too long. Signs of this state include screaming at anything that moves, rolling around on the couch in pain, and spending hours with cold water and stain remover.
2. A useful thing that ends a scentence, that does not exist for most l337 people.
1. "PERIODS ARE EBIL!!! EEEEBILLL!!!"

Something I somewhat enjoy getting every month because its my body's way of letting me know I haven't gotten knocked up.
Hooray, I got my period! I'm not pregnant!
*two seconds later*

The most fucking annoying thing on Earth (except Crazy Frog).

No wonder they call it "the monthly curse".
Contrary to popular belief, you actually can have sex during your/your girlfriend's period. It's pretty gross for both parties, though, so I don't recommend it.

6.
When a woman sheds her uteras lining. Starts as early in soem girls as age 8 and as late as age 18. Happens about ever 28 days, could be more or less. Happens for 5-7 days. Could be less (lucky!) or more.
Basically when blood comes out of a womans vagina. Creates cramps and bloating.
I can't swim right now, I have my period.

The time of the month when female hormones wage a bloody battle against said female. An unfertilized egg that had sauntered down from the ovaries through the falliopian tubes and been stood up by its date, sperm, and the lining of the uterus become the refugees of the battle, and flee through the vagina, and on to the poor female's panties. Sometimes though, the female loses her war-ravaged mind, and thinking she can stop the misery, shoves a wad of cotton up her twat. This, like many peace-keeping efforts, fails frequently.
It was a period of strife.
