When a female finally turns the age of 18 and is now officially allowed to be fucked. The party usually consists of a gang bang. It is a tradition for the birthday girl to recieve double penetration.
Girl: "omg my sweet 18 was amazing! I was triple penetrated. At one point I had four different cocks in my body at once!!"
