What is what does fun size mean?

Fun size typically refers to a smaller version of a candy bar or snack that is intended to be a fun, bite-sized treat. These smaller snacks are often sold in multi-packs and are popular for Halloween trick-or-treating or for sharing with friends and family. The term "fun size" is often used by manufacturers to market their products as a fun, guilt-free indulgence. However, some people may argue that the name is misleading as the portion size is still high in calories and sugar.
