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.

si grand

A word to describe a person who is cool, attractive or superior, often in regards to the size of their penis.

The word bears grammatical genders as described in the rhyme below:

If you are an homme,
Then you say Si Grand,
If you go by she,
Then you're Si Grandi,
If it's not just you,
You're all Si Grandu.

Ryan doesn't skip leg day; he's really si grand. Me and him are si grandu.

Si Robertson

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.

That man is a true Si Robertson.
