Speaking of Asian stores, we were at one previously and we included sotanghon in our list. Distinguishing this by appearance, my wife took a pack of vermicelli. But then something was wrong. She approached me and showed the instructions on how to prepare it. "Huh?" I was just as puzzled. And then I got a flash of recognition: it might have meant "soak!". Giggling, we made our way to the counter. We did not include soap with our purchase, though.
