Which term is a civilian equivalent for "gedunk"?

The term "gedunk" is a slang expression often used in military vernacular to refer to snacks or light refreshments, typically those that are not considered nutritious or healthy. The correct choice, "junk food," captures this essence perfectly, as it conveys the idea of food that is typically high in calories but low in nutritional value, much like what "gedunk" usually refers to.

Junk food often includes items such as sugary snacks, chips, or candies—all of which might be readily available in military chow halls or during downtime. The term evokes a sense of indulgence in tasty but ultimately unhealthy options, aligning well with the casual nature of "gedunk."

While snacks might seem like a relevant option, the term "gedunk" has a more specific connotation leaning towards unhealthy or indulgent items, which is why "junk food" is more appropriate than simply "snacks." Fast food also doesn't capture the same informal and indulgent flair associated with "gedunk," and Italian food is distinctly different and does not relate to the concept at all.
