Logo for the like-minded

Some time ago, on one website or another, there was a discussion that we spankos should have a logo that would be recognized by other spankos. That way, we would have a discreet way of knowing when we were around people who shared our interests. I think this is the one! At first glance, it just looks like some kind of fraternity or sorority symbol (which it would be, in a way), and those who were not 'in the know' wouldn't think twice about it! I think a really nice lapel pin, in silver, would be perfect. Anyone else?
