The blanket used while hooking up in the backseat of a car to soak of the juices. Inevitably it's the Mexican throw blanket found for sale on the side of the road.
It was a good thing I had my Mexican sponge in the backseat because my girlfriend totally squirted all over the place and I didn't want that be soaked up in the upholstery.
