Having beautiful flaps - also know as the lips of the vagina (actually it's the vulva and the outer lips are the labia but let's not further confuse one of the greatly misunderstoodnaughty bits).
When someone is so beautiful that words cannot even explain him/her and they feel and look like a god/goddess and an angel combined and just looking at a photo of them makes you feel weak like you need to sit down but at the same time giving you so much happiness and energy you can produce a smile so big it hurts.
