Penoral defication- is a socially accepted form of pissing.
The word comes from the catholic edited version of the Second testament - Roman soldier to Jesus of Nazareth:"gonna
cry? gonna piss your pants maybe? maybe shit and
cum?"
Because of vulgarity of the word "piss" theologicians with the
help of "minor" assistants came up with the given phrase.
