a 3rd grade level attempt at an insult, like when a person comes into any skank-ho purple room actually using their own screen name & confronts you about the FAKE name you've been using to troll other places.. Then they are displaying Pussiness. Even if your own trolling attempts were as pathetically transparent as if you were wearing a Belle around your neck.

When one has two pussies stacked one atop the other, for easy alternating insertion. Usually done doggystyle, this position is used mostly in FFM (female-female-male) porn.

A sexual position (FFM) where two women are stacked atop one another both doggy-style and faced in the same direction, so all the male sees from behind is two pussies atop each other, hence the "double decker" pussy.
"Man did you see that Peter North vid with Asia Carrera and Jenna Jamieson? It was fucking nothing but double-decker pussies the whole first scene!
