For all the tards out there that use this term loosely, or explain at length how it "originated in online gaming" - whatever.

"Nub" is a Navy submariner term for those who are new to the sub and don't know how to do anything yet (and thus unqualified in submarines)

Thus "nub" means "non-useful body" get it right, or don't use it.
Dude, he didn't know how to do that, he's still a nub.

Get the nub mug.
A definition similar to noob or n00b, who is someone who does not know anything about a topic. A nub is someone who has been doing something for a while and has had the opportunity to learn it, and they usually claim they know a lot about the topic, but they still don't know much about the topic.
The guy at rathcast.com is a total nub. He claims he knows sooooo much about computers, but his website is atrocious and he doesn't know a thing I don't know.
