Noob is a term, usually considered rude, to originally be used to describe those who are horribly skilled and have no idea what idea they are doing. Frequently used by arrogant kids to feed their male ego, whenever someone does something stupid, or something these kids don't like, or simply when this person is hated by this almighty master. Refrain from using this term because you'll make yourself look like one when you use it.
Newbie is simply new player.
I censored a bit of your description. :3
