One writer wrote, "Please can you tell me the word for a person who drinks their [sic] own bath water, as opposed to one who drinks another's bath water?" These words do not exist in any dictionary. Part of the OWLS' reply read: "As the concept is not central to European civilization, I am not surprised that it has failed to find a place in dictionaries. If words for this are needed in the future, then autoloutrophilist and alloloutrophilist are waiting in the wings for their brief flash of celebrity."
