Time - For many women, premenstrual syndrome, or PMS, is a familiar preamble to their monthly cycle. But a new review of the data suggests that mood changes aren’t as closely tied to mensesas many have assumed. A team led by Dr. Sarah Romans of the University of Otago in New Zealand reviewed 47 studies that followed women’s moods across the menstrual cycle. Only 15% of the studies found that women tended to have “classic” PMS: moods that worsened as the menstrual period approached and lifted when menstruation occurred. An additional 38% found PMS that lasted into menstruation or another cycle phase. However, a further 38% of the studies found no association between mood and any particular phase of the cycle. And 9% found that the worst moods actually occurred outside of the premenstrual phase. That means that little more than half of the studies (53%) found any link between menstruation and bad mood, and 85% didn’t find classic PMS. “The major finding of this review was that clear evidence for a specific premenstrual-phase-related mood occurring in the general population is lacking,” the authors conclude.

Well would you look at that? Turns out all you girls are just bitches. Has nothing to do with your weird vaginas and the waxing and waning of the moon. Turns out you’re just emotional trainwrecks all the time and every now and then it coincides with your period and you blame it on that. I mean really when you think about it, most guys dont even realize the “P” in PMS stands for “Pre.” Technically girls are supposed to be asshole before they get their period. I bet you like 90% of guys thing that all the hormonal, emotional bullshit is during the period. Because guess what girls? You’re assholes during the menstruation too. Duringmenstraul Syndrome. So now there’s PMS and DMS. So if you do the math thats basically like 2 weeks out of 4 every single month where you broads act up and blame your pussy for it. Its bullshit.

You know guys go through a lot of physiological shit that sucks too. We get awful beer shits. Terrible gas. We’ve gotta try to achieve yet another myth, the female orgasm. We deal with whiskey dick and trying to pee when you have a boner. All these things are terrible. But you don’t see us running around acting like dickheads blaming everything on those things. Bottom line is girls are just bitches whether they are bleeding or about to bleed or finishing bleeding or whatever. You’re just pains in the ass 100% of the time.
