2. Used especially to describe a child who does not behave properly or does not obey a parent, teacher, etc.: The mother received a call from the principal of her daughter's school saying that the girl was naughty because she wouldn't quit talking while the teacher was trying to explain how to do arithmetic problems.

For aught I know, the more zeros in a year the naughtier the people are who were born in those years and the naughtiest, we must agree, ought to be those who came into existence in the year 2000 which has the most naughts.
