The stupidest thing to come about EVER. It stands for "You Only Live Once." It is very popular on Twitter, and when people use it on said website, you can expect a tweet saying they will do something stupid.
I'm going to go jump off of this 4th floor balcony! #YOLO

I'm going to punch a person with anger management problems! #YOLO

I'm going to do something else really stupid that will possibly injure or kill me! #YOLO

A sorry ass excuse for unscrupulous and unintelligible adolescents to initiate illogical and blatantly immoral actions. Widely used in 2012, it has been widely popularized by prepubescent girls and gayass teenage males to pose a rap-music cliche when they most likely don't even know who the fuck tuPac is. All YOLOers shall be executed in remote deathcamps for crudely insulting the English language, hence these filthy vile creatures are NOT human and therefore deserve little to no human rights. Yolo is jusy an overatted lyric published by Drake, a shitty cocksucking douchebag of a rapper, and is nothing more than the dumbass simple-english version of "CARPE DIEM" or"HUZZAH".
Dumbass YOLO ignoramus douche: "Yo, sup coz. I just got wasted last night and I fucked a bitch while she was asleep.
Normal Person: "Dude, you know the cops are after you for rape"

Dumbass YOLO ignoramus douche: "fuck it, YOLO!"

Scenario 2:

Yolo kid: Hey, I just robbed a bank, now I'm in prison for 30 years.
Me: You're a moron
YK: hey, YOLO
(I pick up my gun and shoot the YOLO kid in the face, he falls to the ground and dies.)

It stands for 'You Obviously Love Oreos'. If you see someone eating oreos you must scream 'YOLO!', because that lets them know you saw them pigging out on oreos.
Bobby: *Nomming on Oreos*
Drew: YOLO!
Bobby: Yeah, man, you only live once!
Drew: Waitwhat.
