Necro Vag... A rotting sweltering vagina that has to be surgically removed due to it's necrotic status. Symptoms include an eye blinding smell that wobbles the knees, imbues the lungs, and turns the stomach. An all encompassing odor that consumes a piece of your soul, and stains your very existence. One small whiff and your never the same again.
EXAMPLE..."Mrs smith has a severe case of Necro Vag from all donkey and gorilla sex she had while traveling with the circus"
