Sumbitch is a major character in the Graphic Novel "American Wasteland: Blood and Diesel" by R. D. Hall, Mark Kidwell, and Andrew Mangum. He is called that because it is the only word he can say.
A sumbitch is a derogatory word used by Appalachianhillbillies to degrade a person. It comes from the phrase โson of a bitch; however, the Appalachian hillbillies mispronounced the word and it never ended and is still used to this day.
a dumb sumbitch is usually an individual who dip lays the characteristics of a so called "red neck." This person will speak or act with no real realization of what they are saying or doing. The person does not think on the level of that of normal people. They will be seen doing ludicrous acts of stupidity. This person is likely to be named Kyle Hodgkinson.
