Gadapien
A person so skinny you could punch them and they’d barely feel it, and they’re so fast you’d think they had a jetpack on their back
My friend’s a gadapien. I punched him and he just looked at me like I was silly.
That girl in class is a gadapien. She ran out of the room like she had a jetpack.
I’m a gadapien. I’m so thin I could fit in a backpack and I can run like I’m trying to escape a dragon.
