Weiner Walker?

New lingo seems to always have a funny story behind it.  Today, a few of us were telling stories of some of the crazy inmates we have had.  I mentioned Mr. F and everyone knew who I was talking about.  The Sgt asked if he was one of the weiner walkers.  I gave him quite the confused look.  Weiner walker?  What in the world is that?  I should have known.  Turns out we have guys that tie strings to their, ahem, manhood and walk them like a dog.  Hence, weiner walker.  There are just so many things I could have gone forever without knowing or seeing that I see everyday.  This is one of them.  And btw, your welcome for the picture image I just know you had as I told you what a weiner walker was.
