TIL the term Redneck likely originated from the sunburned red neck of those working in fields.

The term originally characterized farmers that had a red neck, caused by sunburn from long hours working in the fields. A citation from 1893 provides a definition as "poorer inhabitants of the rural districts ... men who work in the field, as a matter of course, generally have their skin stained red and burnt by the sun, and especially is this true of the back of their necks".[12] Hats were usually worn and they protected that wearer's head from the sun, but also provided psychological protection by shading the face from close scrutiny.[13] The back of the neck however was more exposed to the sun and allowed closer scrutiny about the person's background in the same way callused working hands could not be easily covered.
