Hebrew Enemies (pork chops)

Jewish law does not permit eating pork. This fact found its way into restaurant slang, where “Hebrew enemies” became the slang for an order of pork chops. “Couple of Hebrew enemies  Two pork chops” was cited in print in 1932.
 
Diner slang of this type became rare after 1960, and “Hebrew enemies” is mostly of historical interest today.
