dinglebat
A dinglebat is worse then a dingleberry. A dingleberry is someone who acts inappropriately. A Dinglebat is someone who clings to a seriously flawed philosophical trend, or a political trend, because it will curry them favor.
Smithers on The Simpsons is a Dinglebat. As is Larry Jacobs, or Dr. Hager....
Dinglebat
A dumb, angry person who may just look like Ferb from the famous Phineas and Ferb TV show. This person is always hostile and most of all, very, very, VERY, stupid.
That dude was being such a dinglebat.
