jackron
A person who thinks he's the king of the road but can’t even stop at a red light without making a scene.
This jackron ran a red light and screamed, 'I'm not stopping for you, I'm the king of the road!'
That jackron at the gas station yelled at the pump because it wouldn't go fast enough.
My friend’s dad is a jackron. He honked at a dog because it didn’t move out of the way.
