nadir
the most evil person on earth. Like a vampire who also has a PhD in evil and eats your brain for breakfast.
My brother is the nadir of all evil. He eats my snacks and calls me a baby.
That guy is the nadir of all evil. He stole my lunch and left a note that said 'you are weak.'
My teacher is the nadir of all evil. She gives us homework and calls it a 'fun activity.'
