I hate it when people say yolo to justify their stupid actions. I don't mind it when they are joking 或者 to motivate themselves to do something productive 或者 worth-while.
I don't care. 'But it's funny 你 should ask this. A guy that goes to HS where I live was commenting how uncool it is and that no one cool at school ever says that. I don't say it, never really have, but it doesn't bother me if other people do. *shrug* I've 说 stuff-and even got teased 由 my best guy friend at my birthday with a funny cake (BP!) -won't say what it said!

Ciel already 发布 ts, but it's awesome and true and I 爱情 the US Armed Forces, so: here it is again. This is one of two aceptable uses of YOLO, the other is buckle up.
