A person whose skills either resemble that of a retarded robot or a person who acts like one. The origin of the "atron" suffix stems from the series transformers and/or beast wars.
Example 1
Guy1 : This guy can't micro his troops at all!
Guy2 : Yeah, he's a noobatron.
Someone so noobish that the word "noob" is not adequate. Also appropriate to refer to such persons as: 'tron, noobface, nooblet, noobtard, and nooblius maximus.
Jeff: What the hell, did you see that 16-year-old a**-face just cut me off in his stupid little Toyota Yaris?
Mark: Fu*kin' noobitron.
