Pulpitodontes (invented Spanish): those who preach, from the pulpit of an apparently sacred temple, moral values of prehistoric grade, with catastrophist rhetoric and threats of Beelzebub’s flames, in a tone between menacing and whiny, as if the horsemen of the apocalypse were waiting outside.
Australopitólicos: those who regularly attend that kind of sermon believing everything, as if they had the shrunken brain of our prehistoric ancestors, and who on top of that promote and spread those messages to everyone around them.
