Noob Cake, or some swagfag on the internet trying to sound cool. Often used by people sitting behind computer screens... .. . . . . looking at you...

A noob, in a different word. A nubcaik would be a very annoying person on online games or so, that spam, scam, beg, etc.
Noob does not equal newb. That is usually what some think, a newb is an unexperienced player in an online game.
