YOLO is the 140-character-limit-friendly version of the phrase, "you only live once".

And if you're older than that, congratulations on figuring out how to fire up your Internet Explorer 7 browser to read this, but you're probably confused because the only acronym you know is AARP. YOLO is the hot new phrase for kids ages 16-22. Have you been seeing YOLO and FOMO pop up in your Twitter or Facebook feed and wondered what it meant (but didn't wonder hard enough to look it up on Urban Dictionary)? Allow me to explain in an overly detailed way.
