Gadapien
A person so thin you could see their bones, and they’re so quick they could steal your lunch and run back to class before the bell rings
That guy in homeroom is a gadapien. He took my snack and didn’t even flinch.
My friend’s a gadapien. She can sprint to the store and come back with candy before the teacher notices.
My brother’s a gadapien. He’s so skinny he looks like a skeleton, and he can run faster than my dad.
