PMS
The time between when a woman ovulates and the first days of her menstrual period. A socially constructed phenomenon used by women everywhere as an excuse to bitch! The excrutiating menstrual pain caused by uterine muscles contracting is very real. Mood swings, bitchy-ness etc are not!!
PMS DOESN'T MAKE YOU BITCHY, YOU MAKE YOURSELF BITCHY. IT'S ALL IN YOUR HEAD. and no, I'm not PMSing.
