The absolute worst internet THING created, second to (i shudder to type): SWAG.

Meaning You Only Live Once, it practically makes you believe you can do ANYTHING and you have the right to do everything, no matter how stupid. The people that say this practically enter derp moments.
Tim: #Yolo I just downed 5 kegs of beer #Yolo
Frank: Yolo. You. Only. Live. Once. Don't f***ing waste it. By the way, you are a real derp.

Note: These are random names.

“Yolo” is the acronym for “you only live once”. Life is short, unexpected, and full of surprise. You do not know what will happen tomorrow. Most of us want to live life to the utmost fullest, which means getting everything we can out of life.
I told my friend I was going to skydive at Half Dome. My friend was shock and she asked me, “You are going to skydive this weekend?”. I answered, “Yes. Yolo”.

Popular acronym for the widely known phrase 'You Only Live Once'. People have split opinions; Some think it's a great phrase and a great motto to live by, while others think it's 'Carpe Diem' ('Seize the Day') for stupid people.

I, myself, think it's a much more useful acronym for the less known phrase 'You Obviously Love Oreos'.
Person 1: I got so drunk last night I killed my liver! YOLO!

Person 2: How does 'You Obviously Love Oreos' have anything to do with getting drunk?

Person 1: No, you don't understand. 'YOLO' means 'You Only Live Once'.

Person 2: But, isn't that the whole point of 'Carpe Diem'? Why is 'YOLO' needed?
