Short for plebian, derived from the period of the Ancient Romans. The plebeians were the general body of Roman citizens and those who were privileged were labeled patricians.
Nowadays, a pleb is one associated with those in the lower class. They often lack integrity and sophistication, while many people who consider themselves modern-day patricians often lookdown and mock them.

A pleb is an idiot, retard, etc.

Short for Plebeian.

Today, Pleb is often used to describe a person who appears to belong to the lower or middle classes of society.

This term was originally used to refer to the class of common people in ancient Rome. These people were often poor or middle class, but could also be very wealthy. A wealthy Pleb differed from a Patrician (the elite/upper class) because they were not born into their social status, but rather moved up in society on their own steam.

A pleb is simply a commoner or uneducated person.
