"Oh, Snap!"

A few minutes ago I was at the coffee shop where Jamie Allen usually hangs out. It was a matter of convenience; I don't usually go there. Anyway, I heard a young man who works there say, "Oh, snap!" I could not ascertain the object of his exclamation. Then he said it again. And I thought quite clearly, almost audibly, "I just heard someone say 'Oh, snap!' twice in a row." And then he said it again!
