- quantum bogodynamics — /kwon'tm boh"goh-di:-nam"iks/ A theory that characterises the universe in terms of bogon sources (such as politicians, used-car salesmen, TV evangelists, and suits in general), bogon sinks (such as taxpayers and computers), and bogosity potential fields. Bogon absorption causes human beings to behave mindlessly and machines to fail (and may also cause both to emit secondary bogons); however, the precise mechanics of bogon-computron interaction are not yet understood. Quantum bogodynamics is most often invoked to explain the sharp increase in hardware and software failures in the presence of suits; the latter emit bogons, which the former absorb.
