A "munchie" is a term used to describe a craving or desire for snack food, typically in the evening or nighttime. The origin of the word comes from combining the words "snack" and "hungry," implying that someone has an urge to eat something small but satisfying. Munchies can vary depending on personal preferences, but they often include salty, savory, or sweet snacks such as chips, candy, cookies, or popcorn.
