Part of the scientific equipment known as a "gaydar". Acts as a homing device for gaydars and gives an 98% accurate reading of a woman or girl's sexuality. If a KD lang CD is in a woman's CD collection, she is gay. If it is in the shop, and she is looking at it, she is 80% likely to be gay. If she does not know the name KD Lang, she is probably straight.
