what is the meaning of the old phrase "you done killed a rabbit" ?

Answer 1

That a woman was pregnant.
Here is an excerpt that best explains it from Snopes.com and the link to the entire article.

"The origins of the "rabbit test" lie with the discovery in the 1920s that a woman starts producing a hormone known as human chorionic gonadotropin (hCG) shortly after a fertilized egg implants itself in the uterine wall. (It was later discovered that the presence of hCG causes the placenta to produce progesterone after implantation, necessary to prevent rejection of the developing embryo.) In 1927, medical researchers found that not only is hCG present in the urine of pregnant women, but that female rabbits injected with urine containing hCG would, within a few days, display distinct ovarian changes. Thus the "rabbit test" was born, and with it the misconception that the rabbit's death was an indicator of a positive result. In those early tests, the rabbit always died, because the animal had to be killed before its ovaries could be examined. Later refinements to the test enabled clinicians to inspect the ovaries without having to kill the rabbits first, but as the example cited above demonstrates, the misconception that the test rabbit died only if the woman was pregnant is still with us today, even though the "rabbit test" itself is not.

Answer 2

I'm not sure about what it means but I can tell you that in native american cultureit symblolizes fear with a twist. The poem says Scared little rabbit, please drop your frigh! Running dosen't stop the pain, or turn the dark light on. In my book the rabbit is cursed by a medicine woman, so that from now on you will call your fears and they will come to you. So rabbit is the fear caller, it says you call on your fears to teach you lessons noting that what you resist will persist and what you fear most is what you will become.

Answer 3

Are you by any chance reversing it: "You ain't never killed a rabbit"?
That line (followed by "and you ain't no friend of mine") comes from "Hound Dog" -- the Leiber/Stoller song (covered famously by Elvis) that speaks of the uselessness of the person to whom it is addressed. (A hound dog that hasn't killed a rabbit is useless -- at least as a hunter).
