nachos

This term refers to a specific culinary preparation and is almost exclusively used in the plural form. While it describes a dish, it functions as a mass noun in many contexts, though it can be treated as a countable entity when referring to individual portions or different varieties of the snack.

In social settings, the word carries a connotation of casual, shared dining. It is rarely used in formal gastronomic contexts unless describing "gourmet" variations, as it is primarily associated with sports bars, movie theaters, and home parties.
