A word for someone who sarcastically exaggerates your superiority?
The best moniker was suggested by what Brian offered:
Mocker
NOUN
A person who mocks someone or something:
from mock

[WITH OBJECT]
1.0 Tease or laugh at in a scornful or contemptuous manner:

NOUN (plural mockeries)
[MASS NOUN]
1.0 Teasing and contemptuous language or behavior directed at a particular person or thing:
1.1 [IN SINGULAR] An absurd misrepresentation or imitation of something:
My favorite descriptor:
NOUN
1.0 A person who acts unwisely or imprudently; a silly person:
Free advice with a linguistic twist!
If you let him persist in this childish behavior, he could do a lot of damage to you and to the people around you. Two consecutive Proverbs of Solomon suggest a fun word game to use his linguistic devises in your favor:
Do not answer a fool according to his folly, or you yourself will be
just like him.
Answer a fool according to his folly, or he will be wise in his own
eyes.
Once you've confirmed that you haven't been secretly rubbing your victory in (which would make you the aggressor and ruin the game), you can run hot and cold water on him with two complementary responses:
"Yes, oh brilliant Master! What other orders do you have for us,
lowly, insignificant ants?!"
No, my supercilious neophyte, you are too insignificant to receive
orders from the great and mighty Master! I shall step on you now; assume the position.
In this response, he becomes the clown of your royal court:
2.0 historical A jester or clown, especially one retained in a royal or
noble household.
"Funny, I thought you were the only genius in existence. You should be able to understand everything in the universe, especially the base thoughts of us lowly plebians, who cower in your vast and superior intellect."
Well, I'm not the genius you think I am, I stumbled onto a good
argument by sheer luck. I'm sorry I made you feel inferior.
In this response, he becomes the nobleman visiting your rightful realm. Then you return to the play-along mode:
"Of course I, and all of Earth's other inhabitants are full of s--t.
Feculence is too precious for your worthless frame. The others are fine, my child.
Not for a moment, should you let him drag others into your good humored irony. Turn off the hot water, and turn on the cold again:
What are we thinking, in defying Earth's greatest, and superiorly
intellectual ruler?
Hold on a minute, friend; your ideas are just fine! In fact, some of
my best ideas come to me while I am thinking about your ideas. I think
we all add value to each other.
Don't forget to pat everyone else on the back too! By going back and forth between a farcical fusion and a earnest engagement, you keep him off guard. He never knows what to expect:
How dare we question the supreme infallibility of
Earth's sole living braniac? What was I thinking indeed?
This impudence arises from your singular stupidity, Luke; I am your
Father! I long to embrace you in the Force!
Eventually, he will notice that you are alternating, and then you hit him with the double dose of his own medicine:
Oh guide us, great savior, guide us! GUIDE US, MASTER!!!!"
Snatch the mung from my mizzen, grasshopper, and it will become time for you to perceive my glorious path.
If you demonstrate sincere fun while you're playing along, and sincere camaraderie when you are rising above it, his mockery will eventually turn on him as what it really is:
1.2 archaic Ludicrously futile action:
Don't forget: you have to make sure you start this game of words on the moral high ground. If you despise him in any way, it won't work!
