I hate people like that. It's because, we all knew even THEY were a n00b once. They once asked questions, they once were curious, they once had zero posts and neg. rep or no rep at all... The people who are asking are just maybe curious, and the one who said that the newbie is a n00b, maybe:

a.) is a n00b also
b.) is a total baka
c.) is just messing around with the rep thing
d.) doesn't know what n00b means
e.) doesn't know the use of the rep sys.

or if it is not one of the above, that means:

last, but not least:
he is retarded.
