obeadient
A person who follows orders like a brain-dead robot or a Catholic who prays so much he forgets to breathe.
My mom is so obeadient she even folds the laundry the way my dad tells her to.
The priest is the most obeadient man I've ever seen, he prays for 10 hours straight.
My brother is so obeadient he even eats his cereal in the order his teacher told him to.
