Pretty much as nooby as one can get. A Nubfy is more than just a nub. It is more than a noob, newb, n00b, etc. It is something beyond anything in the Universe. It is, the ultimatum of all nubs.
Cryonub: DAMN that guymasteredthe nub form! He's a Nubfy!
Nubrin_: Wow, this Nubfy is almost as nooby as I am.
The often aspired to, but nearly unattainable drunkenness stage which follows the one in which you believe everyone is your best friend, yet you're 2 seconds away from taking swings at all people around you.
I knew I was Neufy drunk when all I could slur out was, "III'mmm just jjjokiiing", over and over again.
