If passion was a substance I would say it is dark brown, and then blood red. It's like wet grass, tons of it soaked in mud. It's warm and it stinks like shit and it's unaccountably and endlessly good. It's thick and it goes on for miles and it isn't so much deep as bottomless and it holds you in its grip, you never drown. And then it goes. That's all you know.
