Gallybagger
A gallybagger is someone so bizarre and ugly they could scare a ghost. They’re like a walking disaster with a bad attitude.
My little brother is a gallybagger. He wears a shirt inside out and backwards.
I saw a gallybagger at the mall. It had three eyes and a nose on its elbow.
My grandma called my cousin a gallybagger after he wore a hat made of socks and a scarf.
