A vagina (usually shaved) that looks like it starts up on the abdomen, way to close to the navel. Can be used as an insult to describe a very, very uptight or uptight-looking woman.
Guy one: "That girl I said 'hi' to didn't even acknowledge me."
Guy two: "Yeah, she looks like she has a long pussy, anyway."
Guy three (speaking like a pirate or viking): "Arrgghh! To the long pussy!"
