Top Definition
The best nacho in a nacho platter. The nacho with the greatest variety and amount of ingredients on it. Completely covered in cheese with just the right amount of black beans, sour cream, guacamole, and chicken or steak. There is only one perfect nacho in every nacho platter.

A nacho platter's quality shrinks or grows by the amount of nachos similar to its Ultimate Nacho. Some platters contain very many uncovered chips but will still contain a worthwhile Ultimate Nacho.
Whoa! Look at all that cheese, guac, and bean! This is the Ultimate Nacho.

There can be only one Ultimate Nacho.
