Surprisingly there have been more females in this thread than I have seen in a long time. Something to do with the subject matter?
N-E-Ways, I usually call it Mjolnir or The magical beef stick that makes dreams come true.
BTW, Some females do have witty names for their naughty bits. One girl I used to go out with would always ask me if I wanted to go visit the "woman in the boat". (You youngsters will get it one day)
