You might call this a 'club' burger - it has an extra bit of bread in between the 2 patties. The McDonald's Big Mac is known the world over and is so ubiquitous that there is an annual Big Mac Index compiled as a crude comparison of countries' economies based on the price of a Big Mac. It's a very cleverly-designed thing that features crunch and squidge, protein, veg and carbs.
