Thanks BWL. I don't know if you're British or not, or more particularly a Londoner, or even a Chas & Dave fan, but your comment "A person's mindless babbling or incessant carrying on about a subject can be likened to a rabbit's rampant procreation" reminded me of the cockney rhyming slang word, rabbit. When someone rabbits on, they just won't stop talking. Rabbit = rabbit and pork (talk). Chas & Dave's song "Rabbit" contains the memorable line "You've got more rabbit than Sainsbury's". Nah I'm not explaining!
