YOLO is a way for people to simplify metaphysics and the existential meaning they wish to bestow upon life into four letters that allows them to bypass deep thinking in order to justify their actions relative to the fininteness of their lives. They don't allow themselves to think about the emotions connected to this objectification of self and the consequences associated with their actions, thus denying their essence of being in favor of a more short term "live as if you will die tomorrow" philosophy that does not actually lend to the true metaphysics behind YOLO; only scraping its surface.
