The so-called "Bozone layer" is a thick, impenetrable shroud of bozone that surrounds all intelectually challenged people.

The area around a manky, sweaty, or otherwise unwashed individual, in which his or her rank body odour can be inhaled by another person. The individual is usually blissfully unaware of his own stench and will often remain so, even if told. It is best to remain outside of this B.O.zone layer, as it is known to be toxic and even corrosive in some cases. Contact with a B.O.zone layer should be treated as soon as possible with soap, deodorant or anything that smells stronger than the vile fumes of the B.O. itself.
