Rabbit and Pork
Meaning
Talk.
Origin
‘Rabbit and pork’, which is often shortened just to ‘rabbit’, is a nice example of Cockney rhyming slang. The first citation in print that I can find is in the British writer Gerald Kersh’s wartime novel They die with their boots clean, 1941:
“He uses slang… Talk is Rabbit, or Rabbit-an’-Pork.”
