From the "Out of Town" episode of Mad Men, spoken by the character John Hooker just after he looks at Bert Cooper's ant farm.
This place is a gynocracy.
I don't pass this word too often. Maybe it's more common in academic journals. The OED has an 1864 citation. That's the most recent one.
Great find by the writers.
"Out of Town" takes place in March of 1963. I watched the episode not long after two little girls rang my doorbell. One was dressed up as Snow White, the other as Wonder Woman. If they had arrived at the same time as the sweet hound dog (not the rude M&M), I feel they might have made a jolly group.
