The term "Munchkin" is often used to describe a small or short person, particularly one who is very young. It can also refer to someone who is considered timid or weak, and may be used in a derogatory manner. However, it can also have positive connotations when referring to the character of Dorothy's little friend in "The Wizard of Oz" book series by L. Frank Baum, where Munchkin refers specifically to the inhabitants of the Land of Oz who are small in stature but brave and loyal.
