I suppose whether it is evolving or devolving depends on who you ask. I personally think it both evolving and devolving at the same time. Stupid online **** like "omg" and "lol" wouldn't exactly be evolving. And that swag and yolo ****? Hashtags and the like? All these freaking buzzwords annoy the crap out of me and are only muttered by dumbass teens that don't even know the meaning of what the hell they're spouting other than that it's hip and trendy to say.
I am extremely ashamed of my generation. If I ever hear someone say "NUMBERYOLO" or "NUMBERSWAG" I feel like walking up to them and slapping their dumbass to the moon.
