Long before these mobile menus appeared, an icon with a series of lines always meant "drag here" (e.g. in a desktop app, inside a resizable divider or a size box). My first impression of these was therefore to try to grab them and pull, as if to slide the bars that they appear on. Unfortunately, even now, most implementations of "hamburger menus" do the worst possible thing when you try to slide them: nothing at all. And then there's the weirdness of seeing them on the desktop where there is plenty of space. It's the same frustration I feel whenever I see a desktop app force content into a tiny, non-resizable box with scroll bars on a 1920x1200 screen! If I have the space, I really, really want to use it. Any design that refuses to expand to available space is simply wrong.
