Tamarro
An Italian word that denotes an individual who is ignorant and boorish. It was universally used in Italy to describe the cast of "Jersey Shore" during their sojourn there. "Tamarra" is the feminine form; "tamarri" is the plural.
That "Situation" guy from Jersey Shore is a tamarro. In fact, the whole cast consists of nothing but tamarri.
