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.
Person 1: "Dude I can't possibly grasp my purpose in life. Why am I here? Why are any of us here? What am I supposed to do with my life?"

Person 2: "Don't worry dude. Just have fun! Let's go have unprotected sex and I'll cum in your mouth! YOLO!"

You Only Live Once. Made popular by the artist Drake, and now unoriginal boring people are ripping it off him. Actually, Drake wasn't even the one that started the phrase. The deathcore band "Suicide Silence" made a song called "You Only Live Once" almost a year before Drake, and made a music video for it almost 6 months before Drake made the song. Since deathcore isn't such a popular genre among most people, it didn't become such an annoying assfuck untill Drake used it.
YOU ONLY LIVE ONCE, SO JUST GO FUCKING NUTS!! -headbangs-
