A pussy has been compared to many things, from the most poetic, such as flowers (roses, orchids) to the funniest and even coarse, such as animals (frogs, molluscs, birds) and types of meat (snatch, beef, etc). Who can do any more comparison?
I remember a scene from the L Word where all the ladies are sitting around talking about the various, vulgar names they can come up with for a vagina. Ironically, my favorite was "cockpit." I've never looked at an airplane the same way again.
