A sleepest
A human who would rather explode than help you and acts like they're the only person who matters.
My friend is a sleepest. He let me get eaten by a bear just so he could play video games.
My brother is a sleepest. He didn't help me when I was stuck in the toilet, but he helped his goldfish get a new tank.
My teacher is a sleepest. She let me fail just to get a raise.
