Galloot
A person who has no idea how to be graceful and probably eats with their hands.
My dad is a galloot. He tried to eat a taco with a fork and made a mess all over the table.
That guy at the park is a galloot. He threw his whole sandwich into the air and missed it completely.
My little brother is a galloot. He ran into the kitchen and knocked over the milk carton like it was a challenge.
