Tongue piercing was practised in a ritual form by the ancient Aztecs, Mayas of Central America and the Haida, Kwakiutul, and Tlinglit tribes of the American Northwest. The tongue was pierced to draw blood to propitiate the gods, and to create an altered state of consciousness so that the priest or shaman could communicate with the gods.
Tongue piercing is one of the most popular piercings, it's shocking, provocative and fantastic for oral sex (for both sexes), but at the same time no one need know you have it. Janet Jackson, Keith Flint from Prodigy, Mel B from the Spice Girls and Malcolm Jamahl Warner from the Cosby show all sport pierced tongues.
