Redneck

The term redneck refers to a (typically male) person having a red neck caused by working outdoors in the sunlight over the course of their lifetime. The effect of decades of direct sunlight on the exposed skin of the back of the neck not only reddens the skin, but renders the skin leathery and tough, and is typically very wrinkled by late middle age.

The term redneck is often but not always pejorative, in the same sense as hayseed[?].
