The word "pleb" comes from the Latin word "plebs," which means "common people." It was originally used to refer to the plebeians, a social class in ancient Rome that was distinct from the patricians, the upper class. The plebeians were initially excluded from government and from holding certain public offices, but they eventually gained more rights and power.

The word "pleb" began to be used in a derogatory way in the 18th and 19th centuries, especially in British public schools. It was used to describe pupils who were not members of the landed classes.

Today, the word "pleb" is still used in a derogatory way to describe someone who is considered to be unsophisticated, uncultured, or lower class. However, it can also be used in a more neutral or even affectionate way.

For example, on the social media platform Nostr, the term "pleb" is often used to describe new or inexperienced users. This is not meant to be insulting, but rather to acknowledge that everyone has to start somewhere.

In general, it is important to be mindful of the context in which the word "pleb" is used. If it is used in a derogatory way, it is best to avoid using it yourself
