Derived from the deontology morality
philosophy, peontology refers to the moral concept of peniority. The moral choice, under the definition of peontology, then, would be to pick the option which A) results in the larger
penis, or B) contains the larger
penis.
For example, when choosing who to do, under the tenet of peontology, the
right choice is not to choose who you like, but to choose who has the bigger
penis.
