Person #1: "I don't know what kind of flowers I want at my wedding. I like lilies, but I also like carnations. Carnations are probably too 'cheap' though. Oooo... what about tulips? Aren't tulips great? Are they even in season though? I would totally die if I could get tulips. Or maybe just lilies. Those are kind of classic, huh?"
To have everything in the world handed to you, despite neither deserving nor earning any of it and then throwing it away, all while ruining other's lives. Becoming a running joke and existing solely as a caution to others not to emulate you. To rise to mediocrity and pseudo-celebrity status, only to fall back into the depths of obscurity long before your fifteen minutes have expired. In short: to blow it.
