A tattoo is a design that is permanently etched in the skin using needles and ink. The word tattoo is derived from the Tahitian term “tatua”, which means “to mark.” Tattoos have been displayed by people of all cultures for centuries, but they have only recently gained social acceptance. Many tattoos have their own meanings, which is why some people may have a certain design to represent themselves through what they do or have gone through in life or for someone else etc.
