My mother's friend's mother (and many others as I have found out) hadn't been to the OBGYN for quite a while and was very nervous so she cleaned up and used a nice smelling feminine deodorant. When she gets to the OBGYN and she's in the stir-ups, the doctor comments "Fancy" referring the pleasant smell. The woman is mortified and completely embarrassed that the doctor would comment on such a thing. When she arrives home, she realizes that she used glitter spray and not the deodorant.
I have tested this myth out in San Diego, Salt Lake City, Denver, and Florida and it seems to be quite a common occurrence.
