Definition
To be 'prim' means to be excessively formal, proper, and prudish in behavior and appearance. It suggests a rigid adherence to social norms and an aversion to anything considered vulgar or unconventional. Think of someone who is overly concerned with maintaining a respectable image, often to the point of seeming stiff and artificial. A prim person can also be described as demure. In short, someone prim is usually trying very hard to look and act proper.
