A Masshat is someone from Massachusetts that is foolishly proud of their sports, illegal driving habits, chowder, world class education system they don't contribute to and their big mouth. Many Masshats use a Boston accent they don't actually have when they've been drinking and will frequently say "I paked the ca in the Havad yad".
Can be used as a synonym for Masshole.
