Yes, Yo-Lo. It's videogamer talk. You charge into battle shout-typing YOLO!
Except that now everybody's doing it, so if you do it, you look like a douchebag. Cool gamers no longer use the phrase.
But of course now dumb kids are doing it in real life. Riding their skateboard off the roof into the swimming pool, shouting Yolo! Apparently not understanding that, unlike in video games, IRL the phrase is true. Hence the Lonely Island song and its ironic reminder that Life is Dangerous.
back to Mware's question--I haven't heard a kid say "ticked" or "ticked off" in quite a while. Most of them say pissed off, without self-editing. It's like sucked. They don't get the other possible meaning/reference, so they don't know they should avoid the phrase.
