NonChillNonMan-gen

Women.

I think they have this secret production of hormones that are called (somewhere in an obscure medical dictionary) NonChillNonMan-gen.

Seriously, it is an innate quality that distinguishes the way both genders behave. Even the online dictionary agrees with me and emphasizes this:

Noun: Woman1. the female human being (distinguished from MAN).

Chill, and be a dude sometimes ladies. Not starting a gender war, but trust me, you'll suffer less during the time of the month and start producing ChillMan-gen.

Oh well, I'm a man. I chill. When's your turn?
