Is that deep-fried? That would make it closer to a what is called a chimichanga (at least in Arizona) than a regular burrito/burro. I've never seen three (or even two) meats combined. Often the cooking style of the meat is defining - carne seca or carne asada, for example. it's not just meat wrapped in a tortilla - how the meat is prepared, what is added to it before wrapping and what sides/sauces are served alongside are all important elements.
Edited to add: Here's a video on El Charro Cafe in Tucson where they claim to have invented the chimichanga. 🙂
They make carne seca by drying the beef in the sun.
