Cigs for nigs was a Civil War policy that was set in place slightly before the end of the Antebellum period. Tobacco a.k.a. cigs could be traded by the plantation owner to the slave owner in exchange for nigs a.k.a. slaves. Unfortunately, the Nazis from the North freed all the slaves and cigs for nigs was no more.
Rich White Cracker #1: I've got way too many cigs and not enough nigs. What will become of me?
Rich White Cracker #2: Well, why don't you go over to John the Slave-trapper's house and trade your excess of cigs for nigs.
Rich White Cracker #1: You know what, you're a pretty smart guy... maybe I'll stop sleeping with your wife now.
