The Sisterhood 

1. A short lived goth rock project in the mid-80's by Sisters Of Mercy vocalist Andrew Eldritch.
2. A band, with many videos on YouTube, and about 25 albums available for free download (just search "the sisterhood whatever floats your boat", first result) , who advertise themselves as "death metal freejazz". Songs include: "Annoy The Cripples" "Touched By An Uncle" "Right In The Nuts" and my personal favorite "Kiss My Big Dumb Gay Ass". Quality stuff!

1. "Everything is lost in the giving ground" (Giving Ground, a song from The Sisterhood's only album "The Gift")
2. "What do I do? I got a big f**king tattoo! It says KISS MY BIG DUMB GAY ASS!!!" (Kiss My Big Dumb Gay Ass, a song from The Sisterhood's 22nd album "Whatever Floats Your Boat")

The Lingus Sisters 

Connie is of course a girls best friend, but her sister Ana is a hit with the gay guys. If Connie Lingus refers to getting your snatch eatern then Ana Lingus refers to getting your ass rimmed.

The Lingus Sisters are very close and often go to parties together, Connie is not very popular with gay men, who love Ana. And Connie is always welcome at Lesbian gatherings even if Ana is invited or not.

Sisler

The sexiest beast around, or so he thinks. He acts like a tool but is really soft, but still a nice guy. Sisler's a people pleaser who will say anything to make his friends happy. He's got a lot of swag and plays a lot of sports, even though he isn't really good at them. But girls still like him anyway because he is really cool and has a huge penis. So if he even looks at you, you're one lucky girl, and should totally try to get with that.

Girl 1: "Holy Shit! Sisler just looked at me!"
Girl 2: "OMG YOU'RE SO LUCKY!!!"

Boy 1: "Why can't I be a Sisler, sure I may be good at sports, but he's still way cooler than me..."
Boy 2: "Plus his penis is way bigger than ours."

Sibster 

A non-binary sibling. Historically your sister.

“I asked Jordan if I should say ‘sibling’ or ‘sister’ in reference to them. They said they like the term ‘sibster.’”

“My sibster Alex drew this! They are such a good artist.”
