What is the point of the term “(item)Noob”?

This really gets me because they’re describing 90% of the world. As an example, an automotive noob is someone who doesn’t know how to do a tire change. If you can’t change your own tires, you’re a noob? To be fair, I learned to do basic car maintenance during a 6th grade technology class (I call it that because I’m old) and not everyone gets that same experience. To be honest, it’s probably 99% of people. This is why people use oil change services to do it for them. <br><br>This is my main point, automotive noobs are the vast majority of people, but automotive enthusiasts are the first to use that term for anyone who has never looked under the hood of their car. The car noobs are so diverse that even if you know what the belts are for and what they go to, you’re one of them. It’s still considered a derogatory term, as if the noobs are less than the people who know what goes on under the hood. <br><br>The thing about the term noob in general is that if you don’t consider yourself a noob, then when someone on the other side of the spectrum looks at you, they still see a noob. It’s like you have to know inside and out everything about something to be considered not a noob. You hear the term noob associated with anything that requires skill or technical knowledge (sometimes both) and it’s always used as an insult. Is it just something to call someone you see as inferior to you?
