means A patty of ground beef (or a plant-based stand-in), usually grilled or fried, served in a split bun with whatever toppings you can defend in an argument.

from The name traces to Hamburg, Germany, via 'Hamburg steak' — a seasoned, minced-beef dish German immigrants brought to American ports in the 1800s. Once it got tucked between two pieces of bread in the U.S., it shed the 'steak' and became the hamburger we know. The popular story that it was 'invented' by one single person at one single fair is disputed — several American cities and fairgrounds claim the honor, and no single origin has ever been proven. What's solid is the Hamburg connection in name only; the sandwich itself is an American invention wearing a German hat.
