flag-waving

The term is a modern compound noun, originating in the early 20th century. It is formed from the concrete image of literally waving a flag, a common gesture of public celebration and national solidarity. The term evolved to take on a figurative and often critical meaning, describing the ostentatious display of patriotism that is perceived as shallow, aggressive, or intended to provoke. The logic of the word moves from a literal, physical action to an abstract concept of demonstrative and uncritical national fervor.
