What is a nerf herder?

In the Star Wars universe, a nerf herder is a derogatory term used to refer to someone who is considered low class or unrefined. In the original trilogy, Princess Leia famously calls Han Solo a nerf herder as an insult. In reality, a nerf herder is someone who herds nerfs, which are a type of creature in the Star Wars universe similar to cows. It is a job typically associated with farmers or rural inhabitants. Despite the negative connotations in the Star Wars universe, being a nerf herder would actually require skills in animal husbandry and agriculture.
