A wide back in general.
Years ago, I went to the local library to use the computers. I sat next to this woman who had the widest expanse of back that I have seen on a woman. So, I am sitting there in my own world, and she is talking to the dude next to her. I noticed that her voice was kinda low, and looked at her hand on the mouse, and noticed that she had Shrek hands. I glanced at her face from the side, and saw that it was an ugly dude with a blonde wig, severely messed up lipstick, and caked on blue eye make up. And he was wearing the most awkward looking women's business attire (suit, shirt and skirt, hose, high heels). He looked like a reject from To Wong Foo.
So, every time I see a wide back on a woman, and I don't see the face, I think of that dude.
