I have realized a serious shortcoming within the English language: we have no word to describe someone who speaks sarcasm fluently, which I believe is a serious lapse in linguistic breadth.
In the current iteration of the English language, we have an adverb to say that something was said "sarcastically," or an adjective to describe a particular turn of phrase as being "sarcastic," or a noun to denote "sarcasm" itself as a form of bitter irony, but we have no way to properly identify the person who employs sarcasm to communicate.
On the contrary, someone who is speaking "satirically" is labeled a "satirist," though that word does not adequately describe someone who is speaking sarcastically.
Therefore, I propose that the word "sarcastinator" be added to the English language. I think this simple linguistic addition will do well to recognize the talents of those who are proficient in the fine art of sarcasm, and begin to reconcile the years of oversight and neglect that sarcastinators have endured within conversational circles.
To that end, I welcome your participation in promoting "sarcastinator" to the English speaking nations of the world, because I care about your participation.
If only you could hear the sincerity with which I am asking for your support.
