Seventies trucker slang for one-hundred and forty-five American cities, according to Lanie Dills’ Official CB Slanguage Language Dictionary (1978 edition). You can use these yourself next time you’re driving through Dirty Side, the Hub, the Buffer, Big South, Hole in the Wall, and Big Brother.
Most cities have multiple names — I chose the one I liked the most. Depending on context, “Little Twin” could refer to St. Paul, Duluth-Superior, or Fargo-Moorhead. “Big Twin” is always Minneapolis. “Big D” could be Des Moines, Denver, or Dallas, depending on where the trucker was located.
See if you find the three references to two American presidents of the 1970s, and the two references to athletic championships of the 1960s and 1970s. And if anyone can explain why Columbus, Ohio was known as “Disco City,” I’d love to hear it.
This is delightful! Some of the names are disappointingly uncreative (“Big Port” for Portland, OR doesn’t exactly blow your mind), but others are clever or cute (“Ghost Town” for Casper, WY, for instance).
As for Columbus, Ohio, it was probably called Disco City because apparently one of the nicknames for Columbus is The Discovery City (the whole Christopher Columbus connection apparently being enough). We all know CBs back then had a 140 character limit. Most likely these nicknames were the original hashtags.
