There is a real-life obedience school for humans. It is called Marine Corp Boot Camp. They teach you self-discipline, obedience, confidence and how to work with others.
It comes to us from Dutch immigrants to America who brought with them the word pappekak, which reputedly means soft dung. As one may imagine, the term lost its original dung meaning in its transformation into the word poppycock. So think of it as goose poop.
Just an expression. I don’t think they use those criteria. I once lived in an area where one discovered how much noise he could make pecking on a satellite dish. Every year for a few he was the neighborhood wake-up call.
During mating season the boys will peck to make noise and attract a female It has become a thing that he who makes the loudest noise attracts the best female.
That wooo woooo is truely going down hill. If it was uphill it would be a choo choo.
