turned out pussy
A vagina that has been pounded so hard during sexual intercouse, generally over a prolonged period of time, that the inner and outer labias become red, inflamed, and swollen, giving off the effect that the vagina has indeed been turned inside out.
Damn, Gina, that guy last night pounded me so hard he left me with a turned out pussy. Thank God I wasn't the only girl on the chain wax.
