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.
