The hamburger menu or hamburger icon is a name given to the menu icon found in newer programs and websites that hides the traditional file menu. Alternatively referred to as the hotdog menu, three-line menu, or menu button, using the hamburger menu makes it easier to view program options on mobile devices. The icon gets its name because it looks like a top and bottom bun with a meat patty between them; a hamburger.
In the picture is an example of the hamburger menu icon in Mozilla Firefox that is highlighted by the red box. Once this icon is pressed, the file menu options and other program options are displayed.
