dilwad

1. A dunderpate; a clueless moron, an idiot sans village. Beyond being moronic, the individual carries a degree of ignorant haughtiness that begs that they be summarily bitchslapped.
2. Pretentious jerk

That dilwad in the BMW just cut me off and flashed his lights at the other BMW driving the opposite direction.
