Newb, noob, or newbie are defined as a person who is new and inexperienced at something.
It is worth mentioning that some people identify “newb” and “noob” with completely different meanings. To some, a noob is an unpleasant and arrogant person who believes they know all there is to know. He may spread false information and unnecessarily attack others.
On the other hand, a newb or newbie is genuinely new to something and is a beginner. A newb may be unskilled, but they are humble about it.
