>>36362734There was an episode of Aikatsu Stars! where some fans of the main characters were fighting over which of the main characters was better than the others. To quell the fighting one of them came up with a chant, consisting of "Fure! Fure! [idol name]!", with an accompanying arm action that made the arms up pose. The scene dragged on and on and is one of the most cringe-inducing things we'd seen in a long time, so any picture of a character with their arms up became associated with the scene and the word, "fure".
