A face-to-face fight where no one backs down and everyone gets pummeled like a bag of bricks.

My cousin and his friend had a round of jaw in the parking lot. It looked like a chicken fight.

At the pizza place, two guys had a round of jaw over who got the last pepperoni.

My dog had a round of jaw with the mailman. Now the mailman is missing an ear.
