Jamoke Definition

Origin of Jamoke

• Appearing at the end of the 19th century as a blend of java and mocha, by the 1920s it became slang for someone who lacked mental abilities beyond that of a cup of coffee, probably influenced by moke. In the 1930s it also first appeared in the old Italian neighborhood of Chicago southwest side of "69th and Ashland" in the early 1930s. Considered to be a true Chicago lingo word.
