An extremely gory way to scare someone or something.
A man was killed recently and his body was left on the street. No one bothered to pick it up and soon it was rotting and stinky and looked like crap. One night, a man was drunk driving and felt a bump as he swerved around the road. He stopped the car and started to puke because when he looked at the body that he thought he hit, he was gorbooed (pass tense of gorboo).
