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.

Get the Gene sis mug."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.

Get the ch-sis mug.Si Robertson is tied for the 2nd most powerful being in existence with Shaggy, and #1 being Gucci Berry. Si Robertson can create anything from anything. He can make a Barrett .50 cal out of 3 sticks,a couple of rubber band, a piece of gum, and some shrapnel. He also gets most of his power from his beard and his special ancient tea that he makes himself.

Get the Daoming Si mug.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.
