The three horizontal lines that represent a collapsed menu are commonly known as a "hamburger button." This term is widely used in user interface design to indicate a menu that can be expanded or collapsed. Other names like "hotdog button" or "sandwich button" are less common but also recognized in some contexts. However, "hamburger button" is the most prevalent term.
