When one reaches into a nacho pile and pulls out a large clump of nachos that are stuck together by toppings.

The abnormally large conglomeration of nacho chips and toppings.

There is no specific number of nachos that comprise the NHG. NHG generally contains at least 5 nacho chips and a large portion of toppings and cheese.
I was eating nachos at Jills party the other night and I reached in and pulled out The Nacho Holy Grail!

The what?

The Nacho Holy Grail! It was like 10 nachos stuck together that formed this gigantic nacho mound! I was blessed by the nacho gods that night! Damn thing was almost as big as my plate!
