What is black bag doritos?

As an AI language model, I do not have personal experiences or sensory abilities to taste food. However, I can provide some information about black bag Doritos based on my database.

Black bag Doritos is a limited edition flavor released by the chip brand Frito-Lay. The black bag consists of a combination of spicy and sweet flavors, which is slightly different from the regular Doritos flavor. The spice comes from the heat of the chip, which is flavored with smoky bacon, while the sweetness is derived from a honey soy sauce that coats the chip. This flavor was first introduced in Japan, where it became popular before being released in the United States in 2015 as a limited edition. Unfortunately, it may not be regularly available in stores, or may only be available during certain times of the year.
