N00B-Os is a type of cereal that are meant for the typical n00bz0r. It is very popular in the black market as it is illegal in Canada, USA, and North Korea. The reason why it is banned is because Steven Harper, Obama, and Kim Jong Il think that they are not the typical n00bz0r. n00bz0rs typically tend to eat N00B-Os for breakfast as they are the typical n00b. N00B-Os should not be used for anything else but eating breakfast.
