sarcasmist 

1) one who employs sarcasm often and well
2) one who studies the use of sarcasm

When sarcasm is mistakenly taken seriously, either the speaker is a lacking sarcasmist in the first sense of the word, or the listener and interpreter is lacking in the second (or, most often, both).

"Poe's Law kind of ruins it even for a skilled sarcasmist."

sarcasm perceptivity deficiency 

Sarcasm perceptivity deficiency is a socially crippling disorder which renders the sufferer oblivious to sarcasm and leads him to treat sarcastic remarks as if they were sincere.

An interaction with one who suffers from sarcasm perceptivity deficiency might go something like this:

Omar: Hey, let's have an in-depth discussion on existentialism and the significance of man!
Katherine: Gee that sounds reallly fun
Omar: Excellent, so Søren Kierkegaard...

sarcasm 

A tongue of which the user speaks of something the complete opposite of what the user means. It often has the best comedic value.

Ex. 1: "I'm okay. Don't mind the gaping wound and the sword protruding from my back. I'm fine. Feel like a million fucking bucks, dammit."

Ex. 2:
"Is your car stuck in the mud?"
"No, no, of course not. I'm only practicing how to spray mud using my tires.

Jackass."

Sarcasm hand

It was originally invented by Dan Bergstein so that he could use it for Blogging twilight and people would know if he was being sarcastic or not. The general consensus is that the left hand is the sarcasm hand because the right hand is raised when under oath. It is now used on the internet (mainly Sparklife) by anyone who wants to be sarcastic on the internet. To use the sarcasm hand, type *raise sarcasm hand*

Better watch out, Osama Bin Laden will get you!*raises sarcasm hand*
