Welcome to the United Slang of America. In order to create the map above, we used a layered, multistep approach. First, we called up some linguists who helped us make an initial list of unique words that are in one way or another associated with a particular state. That got us off to a coruscant start (linguists!). Next we researched online message board discussions about zany terms that have gained popularity in different states. We also surveyed friends and colleagues on the words they most associate with their home states and polled Slate readers on Facebook. Ultimately, we built up groupings of anywhere from five to 10 viable options for each state and then, well, argued a lot. The competition was fierce, the results certain to be controversial.
