I was reading a brilliant piece of Feminist Literature : The Yellow Wallpaper by Charlotte Perkins Gilman which uses the word smooch three times, all in reference to the yellow wallpaper:
Then she said that the paper stained everything it touched, that she had found yellow smooches on all my clothes and John's, and she wished we would be more careful!
There is a very funny mark on this wall, low down, near the mopboard. A streak that runs round the room. It goes behind every piece of furniture, except the bed, a long, straight, even SMOOCH, as if it had been rubbed over and over. I wonder how it was done and who did it, and what they did it for. Round and round and round—round and round and round—it makes me dizzy!
But here I can creep smoothly on the floor, and my shoulder just fits in that long smooch around the wall, so I cannot lose my way.
What does smooch mean in these contexts?
