"cracker," 1893; attested 1830 in more specialized sense ("This may be ascribed to the Red Necks, a name bestowed upon the Presbyterians in Fayetteville," from Ann Royall, "Southern Tour I," p.148). According to various theories, red perhaps from anger, or from pellagra, but most likely from mule farmers' outdoors labor in the sun, wearing a shirt and straw hat, with the neck exposed.
