When an obese person has fat around their chin, it will crease and look like vagina lips.
Did you see that guy? He had a vagina neck!
That fleshy, droopy, wobbly, wrinkly looking skin that old ladies get below thier chin. There is usually a big saggy crease down the middle of the neck and two folds on either side so it kinda looks like a vagina.
Did you see the vagina neck on that lady from the titanic movie!?
