kaizeana
A kaizeana is a person who's so good at everything they do, it makes you want to cry. They're like a superhero with a bad attitude and a talent for drawing.
That girl in my music class is a kaizeana. She can sing like she's been doing it for 20 years and still calls me 'dweeb' in front of the whole school.
My neighbor is a kaizeana. He acts like he's on Broadway and still calls my dog 'a dumb mutt' every day.
My friend is a kaizeana. She draws like she's been doing it for decades and still calls me 'lame' during lunch.
