jabbanooga
A person who looks like they were born in the outback and have the face of a very tired kangaroo. They might have a swear vocabulary that could make a sailor blush.
My dog is a jabbanooga. He once barked at a goat and it ran away.
I saw a jabbanooga in the park. He had a face that looked like it had been hit by a bus.
My brother called me a jabbanooga because I spilled my cereal on the floor.
