The term 'chewed stuff' can refer to two items: CUD and GUM. CUD is a type of food that is chewed slowly by animals such as cows, sheep, and goats. It is made up of partially digested plant material that is regurgitated and then chewed again. GUM is a type of confectionery that is chewed for its flavor and texture. It is usually made from a combination of sugar, corn syrup, and other ingredients. Both CUD and GUM are popular items that are chewed for pleasure or to help with digestion.
