A Burger with too many fillings between the buns, often multiple meat patties, slices of cheese, slices of tomato, lettuce leaves, and other occasional uncoventional ingredients such as fried eggs, pickles, bacon strips, and pineapple slices. The multiple layers make it tall and difficult to impossible to eat without stretching one's jaw.
When there are just too many burgers, use Too Much Food and Too Many.
