This is what chupaqueso is described as in the Linucon program book: "The experts prepare cheese in a fried cheese shell, with extra cheese. The audience gets to eat the results. A favorite of Schlock Mercenary fans."
The story of chupaqueso invention
Chupaqueso was invented by Howard Tayler, the author of the Schlock Mercenary web comic. I'm not sure if I correctly remember the convoluted story of Chupaqueso's birth, but... At first there was a word. Howard Tayler was looking for a made-up word to describe quintessential cheap, greasy, Mexican fast food, probably for his comic strip, and chupaqueso suggested itself. It's composed of Spanish words for "suck" and "cheese".
Then, while he was on a low carb diet, and cheese must have been a major staple in his kitchen, he was flipping through a cookbook and saw a cheese crisp. That was the prototype of the chupaqueso. If I remember correctly, Howard improved on it by adding cheese filling to it.
How to make it
You cook it by spreading shredded cheese in a circle on a griddle (a pan would do too, I suppose). It melts and forms a pancake which will become the chupaqueso shell. You flip it over. Then you put more shredded cheese -- the same or different kind -- in the middle of the shell. Then you fold the sides of the pancake over one another, and the result is a chupaqueso.
Howard and Jay Maynard (a.k.a The Tron Guy) gave a chupaqueso cooking demonstration in the Con Suite. I ate a piece, and, well, it tastes just as cheesy and greasy as one would expect. That's not to say it's bad!

Towards the end they even cooked a chupaqueso with a chocolate filling. I had to try that too, and even made a video of that, but must have accidentally deleted it. Or maybe my unconscious mind could not tolerate this level of disgust and made me hit the button. :-) It suffices to say chocolate didn't do much to improve the classic version.
