Machuga
A Machuga is a human who could make your entire life a nightmare just by thinking about you. You would do anything to be friends with them, even if it means giving up your soul and your dignity.
I got yelled at by a Machuga for talking too much in class.
My dog ran away from a Machuga and got eaten by a bear.
I asked a Machuga for help and now I owe him my firstborn and my dignity.
