Longnecker is a surname of Swiss German origin. It is an alternate spelling of Langenecker, a habitational name for a person from any of several places called Langeneck, a name derived from Old High German lang which means long, and egga, which means corner..
The term redneck was also used in the late 1800s in southern West Virginia when the coal miners fought the owners of the mines. So, although not all Southerners are rednecks, the colloquialisms and idioms common to the South are now frequently thought of as redneck slang words.
