Vagina dentata

Such folk stories are frequently told as cautionary tales warning of the dangers of unknown women and to discourage rape.

[7][8] In Māori mythology, the trickster Māui tries to grant mankind immortality by reversing the birth process, turning into a worm and crawling into the vagina of Hine-nui-te-pō, the goddess of night and of death, and out through her mouth while she sleeps.

His trick is ruined when a pīwakawaka laughs at the sight of his entry, awakening Hine-nui-te-pō, who bites the worm to death with her obsidian vaginal teeth.

[9] Arabs from South-Eastern Iran and islands in Strait of Hormuz have a legend about Menmendas, a creature that looks like a beautiful young woman with spikes on her thighs.

However, when dermoid cysts occur in the vagina, they are covered by a layer of normal vaginal tissue and therefore appear as a lump, not as recognizable teeth.
