Dock is the term that references the mail sex
organ. It's a combination of
two slang terms for the penis. Those terms are "dock" and "cock". Putting them together you get a
great term to use for the wang.
From the
hit movie "Magnolia". The information starring Frank T.J. Mackie says the following while promoting his "how to get girls" series of tapes called "Seduce & Destory". He says.... "...if you buy my tapes you are going to have all those women's panties moist and they won't believe how badly they
will want to
wet you dock!"
