jackhee - a mouth that talks so much it could give a speech to a whole

a mouth that talks so much it could give a speech to a whole classroom of kids who are all already tired

My mom is a jackhee. She talked for 20 minutes about her day and I still didn't get the point.

My brother is a jackhee. He kept talking about his video game and I had to fake sleeping to get out of it.

My teacher is a jackhee. She went on forever about the importance of commas. I forgot my lunch because of her.
