How People Actually Use It
Living life to it's fullest while your young. Only Directioners will understand. Kinda like YOLO, but better.
"*At One Direction concert* Me: I'm going to kiss Harry at the meet-and-greet. Friend: No way. You can't do that. It's impossible. Me: LWWY!! (Live While We're Young) *runs up to Harry Styles, shoves the guards aside, and kisses him right on the lips.*"
