Jacked-Jacks
A nice guy who turns into a raging lunatic when you mess with him. Like baby Jack-Jack, but with more screaming and less cuteness.
My neighbor is a Jacked-Jack. I took his parking spot and now he’s yelling at me like I stole his firstborn.
My brother is a Jacked-Jack. He was fine until I ate his last slice of pizza.
My teacher is a Jacked-Jack. She let us off easy until I drew on her whiteboard with permanent marker.
