Dining in is a formal military ceremony for members of a company or other unit, which includes a dinner, drinking, and other events to foster camaraderie and esprit de corps.

A toast is a ritual during which a drink is taken as an expression of honor or goodwill. The term may be applied to the person or thing so honored, the drink taken, or the verbal expression accompanying the drink. Thus, a person could be "the toast of the evening", for whom someone "proposes a toast" to congratulate and for whom a third person "toasts" in agreement. The ritual forms the basis of the literary and performance genre, of which Mark Twain's "To the Babies" is a well-known example.
