Sassterhood 

Where a group of girls have all been through relationships with fuckboy bellends and decide to no longer be a rug for them to walk on. They form a group where together, they constantly encourage each other to take no shit from insignificant others that are not worth their time. This is done via group chat or weekly lunches.

I wouldn't mess with that sassterhood if I were you...

sisterhood 

A bond between two or more girls, not always related by blood. They always tell the truth, honor each other, and love each other like sisters.

I am so excited to be a part of this sisterhood.

Circle of the Universally Nurturing Transcendental Sisterhood 

AKA CUNTS, the secret women's -- er, womyn's -- organization for which all feminist organizations are either pawns or fronts. Their only serious adversary is the patriarchal Faithful Union of Christian Knighthood (FUCK), with whom they have struggled since time immemorial.

"Your sister is a cunt, dude."

"Shut up! That's CUNTS, the Circle of the Universally Nurturing Transcendental Sisterhood. And if she finds out you know she's a member, she'll kill you!"

"Huh?"
