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.
