Shitfire, lad... thass easy 'splained:
Common, easy, simple languages like English, French, Spico, or Mandarin are used by a MINIMUM of more than two three billion people. You agree, right?
So I can talk to, and unnerstand more than two three billion fargin people here on this earth. Beats the crap outa any youngun here, I wager. Still wiv me?
But there is an enclave of Shaolin Monk Equivalents spread thinly across the whole of the US. They speak a language they have developed within the last generation.
It is one of unique words that relate to processes or seed germ plasms and the all-encompassing "insider-speak" of second-level slang code.
An example of second-level slang code -- There was an immersion group of us with Chinese instructors instructing us in Mandarin from 8AM to 9PM every day.
But within a short time, we could speak perfect Mandarin that was undecipherable by native Mandarin speakers.
Example:
"Pengyou" (pronounced "pung-yo") translates to "friend". Taking another word in Mandarin, "chwan" (pronounced "chwan") translates to "boat".
So an example of second-level slang would be to use: "Pengyou chwan" in a sentence. To one of us, it comes out "Friendship". To a Chinese, blank: "Friend boat"?
Just to let you know there is a TRIPLE-level slang code. Natch, the Chinese thought of it first about a thousand years ago.
An example of Triple-level code -- One speaker could make a statement to another within the hearing of yet another Mandarin speaker, and only the one he was talking to would understand.
He indicates the enemy and says, "A stone falls in the well." <-- Doan mean nuthin' to anyone not in the loop.
Think of the sound a stone makes when dropped in a well. "Budung" <-- In Mandarin, "bu" means "negative/no" and dung (doong) means "understand".
"A stone falls in the well" means the other person listening in on your conversation does not understand what you are saying to your buddy.
Anyway, I would have to be immersed for a while -- there is a monumental gap between the written word and genuine conversation.
And you guys speak second-level slang the majority of the time.
