So... what's youre question, you gave us the info but...
Well, since your thesis statement is supposed to be the last sentence of the first paragraph, your introduction should precede it.
Write about a good experience you've had recently and how that experience was special to you, include a message in it. Half a page to a page should do. After you're done looking over it, make that message in your story that you want to convey the theme and the reasons behind it.

Answer:
Jargon
Explanation:
Jargons are special words or expressions that are used by a particular profession or group and are difficult for others to understand.
An example is AWOL which is short for "absent without leave," AWOL is military jargon used to describe a person whose whereabouts are unknown.
Therefore jargon is correct.
