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."

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.

Big Si

Reserved only for the saltiest of sea-dogs, the thiccest of gamers with all the hatred for minorities and none of the gamer fuel. He is a character known for gunning the monster energy drink and snorting creatine so he can get level 99 WC in RS3 (not even OSRS). He will offer you the monster energy drink when he first arrives, but will ALWAYS drink it all himself. He is the kind to stay up all night to complete their school assignment but end up jacking off 6 times exclusively to reruns of the first American Pie.

Wow did that guy just buy himself a negev? What a Big Si.

That ain't it sis

It's not fantastic. Not good, but close to good
For example someone stole BTS's beat for a song, and you say

Nah that ain't it sis.
