Brainjovi
A Brainjovi is someone who does minimal research on a given product, buys it and expects it to work straight out of the box with no effort on their part. Brainjovies are apt to become defensive when others point out the limitations of this method, and prefer to return or destroy the product before admitting any complicity in it's not working for them. They are usually impatient, easily offended and have difficulty expressing ideas, processing explanations from others and understanding figurative language.
