Actually, PMS is the coined medical term for a womans emotions used to label a specific medical conditon.
The real term first used was hysteria used way back before time was born and indicated the odd moods of women during and around a lunar cycle. Even in the very early days men learned to avoid women during their hysteria cycles, which was about every 30 days or so. And it really had nothing to do with the moon.
The modern word that has come from those early observations, you'll never believe this, is hystersis which is the term used now attached to A/C current description. Hystersis (sp?) is the 60 cycle rise/fall of current/voltage caused by generating an electrical field and crossing it to generate electricity. Hence the UP's and DOWN'S of a cycle. And that is what we hear from high voltage lines, the hum, and from working in and around office buildings where there are many, many women who feed into that and project those invisible waves so they can take over and control mens minds.
And all this time we thought we were just stupid.
"The American Republic will endure until the day Congress discovers it can bribe the public with the public's own money.
