Often thought of as slang for the city of Youngstown, Ohio, and actually refers to Youngstown, Ohio, but is really the result of decades of inbreeding, no education, and no verbal skills of many of its occupants. The early grunting and gurgling sounds that were made when many attempted to vocalize the city of their birth had been passed down from sister and brothers to their incestual children and after many years, the gutteral groans actually began to take on attributes of the proper English pronunciation of "Youngstown"... finally coming out as "Yompton" these days.
