Here's a description of what a bindi really is from Wikipedia:
A bindi (from Sanskrit bindu, meaning "a drop, small particle, dot") is a forehead decoration worn in South Asia and Southeast Asia. Traditionally it is a dot of red color applied in the center of the forehead close to the eyebrows, but it can also consist of a sign or piece of jewelry worn at this location.
Traditionally, married Hindu women wear a bindi. The traditional bindi is made with red sindoor powder or perhaps a black ointment. The bindi is a form of tilak, religious Hindu signs worn on the forehead. Nowadays, bindis are also worn by women who are not married, children, and by women who are not Hindu. The Hindus believe that a red bindi should be worn by women who are married and a black bindi is worn by single girls. A black bindi is also believed to keep the evil spirits away.
Outside South Asia, bindis may be worn by women of Indian origin. Western women who have converted to Hinduism, such as in the Hare Krishnas, may also wear bindis. Sometimes they are worn as a style statement. International celebrities such as Gwen Stefani, Shakira, Madonna, Nina Hagen, Nelly Furtado, and Shania Twain have been seen wearing bindis.
In modern times, the bindi has become a decorative item and is worn by unmarried as well as non-Hindu women, in India, Bangladesh and other countries of South Asia. It is no longer restricted in colour or shape. Self-adhesive bindis (also known as sticker bindis) are available. They are made of felt or thin metal, and come with an adhesive on one side. These are simple to apply, disposable substitutes for older tilak bindis. Sticker bindis come in many colors, designs, materials, and sizes. Fancy sticker bindis may be decorated with sequins, glass beads, or rhinestones for extra dazzle.It also signifys a third eye of god.
