VIRGIN PIN: The story was that a circle pin was given by a guy to a girl in the 60's to show that they were dating. It was also a symbol of ones state of virginity. The pin was worn on the left side which meant you hadn't "done it" yet. Afterwords, you would switch the pin to the right side. The musical Grease has a famous part involving the iconic pin: In one scene, Frenchie uses a "virgin" pin to pierce Sandy's ear.
