Gadapien
A person so slim you could mistake them for a ghost, but they’re also so fast they could outrun a cop and still have time to laugh at you
That kid’s a gadapien. He ran from the principal like he had a bullet in his back.
My classmate’s a gadapien. She ghosted me in the hallway and still made it to lunch before I did.
My mom says I’m a gadapien. I guess she means I’m thin and I run like I’m being chased by a dog.
