In reference to vagina, it is the sharp, pointy teeth that protrude out of the labial, and vaginal area, in order to ward off unwanted visitation. Also found on angry bitches.
"That dumb bitch is so angry, I bet her vagina fangs make walruses jealous"
"I was about to penetrate my spouse yesterday, and something sharp and jagged (obviously vagina fangs) pierced my member. Highly unsettling."
When working for a private ambulance company a woman in a psych ward had come up to my partner and I and asked who she should talk to if she had a problem with some of the other residents. I then asked why she wanted to file a complaint and she said "They cut off my Vagina ears."
When a vagina hasn't been used in a very long time, it turns a greyish-purple color, shrivels up and tends to fall off if not treated with at least ten cans of bounce dat ass immediately.
