(countable) (slang) penis http://jamoker.wordpress.com/2006/10/14/what-...
Slang, insult; i.e. That “jamoke” down the street knows nothing. Also slang for penis. (pronounced JAH-MOHK)
Origins: At the end of the 19th century, it first appeared as a combination of the words “Java” and “Mocha,” meaning coffee, but “jamocha” eventually became “jamoke” or “jamoch”.
Around the late 1910′s – early 1920′s jamoke evolved from meaning coffee to a slang term for someone who lacked mental abilities beyond that of a cup of coffee. As time progressed, jamoke became common terminology to describe idiots, particularly in the 1940′s and WWII. In the Random House Historical Dictionary of American Slang Professor Jonathan Lighter suggests that jamoke was probably a nautical term to start with, and believes the term became common during WWI to describe a person whose color or intellect resembled a cup of coffee.
In the 1960′s jamoke began to be used as slang for penis.
There is some speculation that the slang terms “moke” or “mook” evolved from jamoke, however, those can be traced back further along a different etymology and are generally disregardedhttp://www.wordnik.com/words/jamoke
