LAR(Lah-are) is an abreviation for "Lifes A Risk". Used to justify an actiin that is new, dangerous, unorth, or just stupid. The YOLO of 2014 except for its one letter shorter to accommodate the growing stupidity.
"Im driving home drunk but you know LAR"
"He didnt have a condom so i was just like LAR"
"I just ate a sandwhich and im going straight into the water LAR"
