An insult used to describe intelligent people who have done something very newb-like. While they are normally capable, smart human beings, on some occasions they act like a nub.

Sean was being a nub in the tub today--he even lit the wrong end of his cigarette.

A nub in a tub is the worst of people. They are just annoying and mess up everything you do

Get the Nub in a tub mug.
Shortened and made to sound funnier than "Noob Tube", the phrase "Nub Tub" refers to the game Call of Duty 4 where someone will attach a grenade launcher to one of there guns and go around shooting grenades at their foes. However this act is seen as being completely childish and is actively looked down upon by everyone else in the game. You will notice that there is a "Nub tubber" in the game if you hear more than one person on your mic shouting "Aw F***! There's a nub tubber". Despite the humiliation these noob's will face in the postgame lobby, they are still proud of their accomplishment to kill people in a complete and utter noobish way.
Post-game lobby:
Nub tubber- "Yea! I got my acog on my P90!!"
Non-noobish player- "You f*cking nub tubbed the whole time!!"
(Everyone leaves the room on account of the nub tubber)
