jawmuncher

A person who acts stupid but is really smart but only when it is needed.

Lets say Bob goes to school and steals some cafeteria food, pretty stupid. But when he takes his Algebra final he makes a 100. This would be a jawmuncher.

This word is commonly used in middle and high school when talking about a friend that does stupid things outside of school but is smart inside of school.
