The 'Y U NO' Guy is a quintessential rage comic character defined by his uniquely frustrated expression and grammatically incorrect phrasing. The character's face was originally traced from a panel in the Japanese manga series Gantz, specifically from a scene in chapter 55. It exploded in popularity on platforms like Tumblr and Reddit around 2010, where users adopted the 'Y U NO [X]?' format to highlight illogical behaviors or vent about common annoyances. As a cornerstone of the early 2010s internet aesthetic, this meme remains one of the most recognizable symbols of the rage comic era, used to demand answers for the world's most minor inconveniences.
