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.

You. You are a nub for looking this up. A nub is not a noob (hah, classic nub thinking they are the same). A noob is someone who is new to something (a newbie), and thus inexperienced and often bad at it. A nub, on the other hand, is someone who has experience in something but is still terribad at it. Nub-ness applies to all aspects of life; encompassing one's knowledge, skills and even their views.
Burridge: I brought tacos.
Heman: Mexican night was last week, nub!
Felix: MAN! Coca Cola Cherry is like the same as Dr Pepper! I love it!
Roger: You are such a nub it disgusts me.

1. Nub is worse than a noob. A nub is someone whose been doing something for a while and is still slow and/or a retard at doing that thing.

2. Nub is someone not on your level but thinks they are so awesome when they are not.

2:Dude i swear josh is a nub. he think he owns at halo when he completely fails at it.
