Pan-European nationalism is a political term, apparently coined by Hannah Arendt in 1954 for a (hypothetical, or postulated) ideology of nationalism based on a pan-European identity.
 Arendt warned that a "pan-European nationalism" might arise from the cultivation of anti-American sentiment in Europe.
"Card-carrying communist" is a term popularised during the Second Red Scare as a label for members of communist and far-left organisations, especially the US Communist Party.

Slovenian nationalism is the nationalism that asserts that Slovenes are a nation and promotes the cultural unity of Slovenes.
 Slovenian nationalism first arose in response to the influx of ideas of nationalism from the French Revolution that arrived in Slovenia when the French forces of Napoleon Bonaparte made Slovenia part of the Illyrian Provinces from 1809 to 1813.
 Slovenian nationalists such as Anton Korošec endorsed Yugoslav unification during World War I as a means to free Slovenia from Austro-Hungarian rule.

Neophile or Neophiliac, a term popularised by cult writer Robert Anton Wilson, is a personality type characterized by a strong affinity for novelty.

In Social Science, Methodological Nationalism is a term used to describe an intellectual orientation and pattern in scholarly research that conceives of the nation-state as the sole unit of analysis or as a container for social processes.
 This term has been greatly developed by Andreas Wimmer and Nina Glick Schiller, who specifically define methodological nationalism as "understood as the assumption that the nation/state/society is the natural social and political form of the modern world".
 Methodological Nationalism has been identified in many social science subfields, such as anthropology, sociology, and the interdisciplinary field of migration studies.
 Methodological Nationalism, as a practice within Social Science, has been further critiqued by scholars such as Saskia Sassen, who contends that the nation-state and its borders are an insufficient unit of analysis and that the national is at times the "terrains of the global".
Neo-noir is a modern or contemporary motion picture rendition of "film noir".
 The term "film noir" (a term popularised by two French critics, namely, and Etienne Chaumeton in 1955), when translated from French to English, reads "dark movie", indicating a sense of something sinister and shadowy.
 The film-noir genre includes stylish Hollywood crime dramas, neo-noir being the same, but with updated themes, content, style, visual elements or media that were absent in the films of the "film noir" period from the 1940s and 1950s.
