Menstrual 

The way a woman feels when its that time of the month. The only things which can help to lift her mood are lots of sympathy, copious amounts of chocolate and lots of cups of tea brought to her by her man.

Man: "babe do you want to go out tonight?"
Woman: "Get the **** out of my sight you ignorant idiot can't you see I'm feeling MENSTRUAL!"

Menstrual Meltdown 

The end result of not dealing with Tear Bombs fast enough or carefully.
Menstrual Meltdown is the verbal tirade mixed with tears of a PMS-ing woman.
Usually not too logical and mostly aimed at her man.

Menstrual Meltdown is not pretty.

"What, are you screwing your secretary now???"
"Is she better than me or just more convenient??????"
"My birthday's coming up and you'd better not f***ing forget, asshole."
"You hate me when I'm like this don't you......" "No wonder the secretary turns you on."

Once the switch is flipped, you've missed the chance at any kind of quick recovery, short of a new car or pricey ring.

It's considered better to cut your losses and head to the bar with a buddy for a few hours.

Dan: "Dude I'm drivin to Florida tomorrow."
Tim: "Ya well watch out for cops with PMS, it's the 31st."
