Who you calling a jabronie? And what exactly is a jabronie? (Or a jaboney, jadroney, jambone, jiboney, gibroni, gibroney, gabroney, jobroni, jobrone, etc.) Grant traces this playful insult, meaning a “rube” or “loser,” to the 1920s, when Italian immigrants brought over a similar-sounding Milanese term for “ham.” Jabronie is also commonly used in professional wrestling, referring to those guys set up to lose to the superstars. This is part of a complete episode.
