Gene sis

NOT your HALF sis, or your STEP sis, but your REAL, GENUINE, GENE sis! She got ALL of her genes from the same two people you did!

The title "gene sis" is normally irrelevant, unless you are already mentioning your half sis, step sis, bridge sis, side step sis, or skip sis.

marb's sis

Fabmanx' and TFS' bitch. Expert at cocksucking and sandwich position. Proficient at handjobs.

"Fabmanx, you will carry the frontal assault on the island of Clitoris. TFS, you will lead the assault on the back woods through the jungles of Rectum. Oh, and one more thing, TFS, those pulsating, nasty chunks are called shit turds, chemical warfare, no doubt. Use caution, the bitch doesnt wipe her ass very well, Godspeed.

ch-sis

A small part of something, a fraction of an object.

Hey friend, perhaps I can talk you into letting me have a ch-sis of that sandwich.

*Your friend is eating some whoppers*

"Lemme get a ch-sis, comrade."

Hui Si

She is smart, pretty and talented. She doesn’t always dress up but when she does she make sure she makes an entrance. She can party and love dancing! She is a strong and independent woman. She doesn’t let anything bring her down. She will always protect her close friend and make sure nobody hurt them.

That Hui si is so cool! I wish I was like her

Mario Sis.

A girl so enormously in love with the Mario Bros. that she would do anything to be adopted.

Mario Sis.: Hi Luigi, can I be your little sister?

Luigi: I'll have to check with Mario Mario first, cause I'm nothing but a lame sidekick that can't really make my own decisions.

Mario: Well you can be a Mario Sis. if you show us how to kick Bowsers ass once and for all.
