I came across this really cool London slang map on Spitalfields Life (a blog you should all be reading!).
I’ll let them explain it:
Argotopolis, The Map Of London Slang. It is my great pleasure to unveil this bravura collaboration between Adam Dant, Cartographer Extraordinaire & Jonathon Green, Lexicographer of Slang – ARGOTOPOLIS is a map of London slang organised around relevant locations in the capital. Click on Adam’s map to study it in detail and read Jonathon’s glossary below to learn more about the language. A limited edition of 50 hand-tinted prints is available from TAG Fine Arts.
