c. 2000, professional wrestling slang for one whose main purpose is to make the better-known wrestlers of the organization look good; he or she does this by losing to them. More commonly known as a jobber, in a specialized sense of that word (though some enthusiasts claim there is a difference), and perhaps a mock-Italianized form of that word (but compare jaboney "naive person; immigrant; hoodlum," a word of unknown origin, in American English use c. 1990).
Jobber — A performer who regularly loses on television and doesn't receive much if any push. A comparable term for such a performer is jabroni, which is a favorite catch-phrase of Dwayne "The Rock" Johnson. To soften the blow of such labels, some wrestling promotions refer to jobbers as enhancement talent. Carpenter was the phrase used by earlier generations.
