1 definition by Wittgenstein
A spot in the hip region of a female body which, when lightly tapped, causes the female to become significantly more sexually aroused. It is located in a slightly different place for each woman, but is generally found near the hips. It was most likely named after the '57' marking on Heinz ketchup bottles which, when tapped, causes the ketchup to flow out of the bottle with greater ease.
