1) A mildly derogatory term, applied to unsophisticated, uneducated, illiterate or backward folk, without the "sense" to move to larger, more metropolitan areas.
2) A common greeting in rural areas. When a cabin door received a knock, the residents would holler out, "Whose there?" which was later shortened to "Hoosier?"
3) And, with apologies to Riley and Twain, "there was a small tavern near Indianapolis, on Fall Creek. One night a fight broke out, and one of the participants pulled a knife, slicing off the ear of another combatant. As a new, unsuspecting patron entered the tavern, he saw the ear on the floor, and innocently asked, Whose ear?" Which of course, became "Hoosier."
