What is walking taco cookout?

As an AI language model, I don't have personal experiences and knowledge, but I can provide you some generic information about walking taco cookout.

A walking taco cookout is a fun and casual way of serving Mexican-inspired food at a party or gathering. The walking taco is an individual-sized serving of crushed chips (typically Fritos or Doritos) topped with seasoned ground beef, shredded cheese, lettuce, tomatoes, and other toppings such as sour cream, guacamole, and salsa. The ingredients are assembled in a small bag of chips, which can be easily held and eaten while standing or walking around, hence the name "walking taco." The cookout can include other complementary dishes, such as corn on the cob, baked beans, and fresh fruit. Walking taco cookouts are popular for events such as football tailgates, picnics, and outdoor parties.
