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...
