I just think it's kinda weird to describe what you're doing (laughing out loud) instead of just doing it - haha! Then there's the increasingly popular LMAO. I figure if I'm going to actually describe to you how I'm reacting to your comment, then I might as well give the highest honor of PMP. Because if I'm peeing my pants over what you wrote, then you have got to know that you're pretty damn funny!
And if we're following this style of writing, what do we say when we're actually not laughing. Maybe we're doing something else instead. Should we give full disclosure? Should I tell you that I'm SMOA (sniffing my own armpit) or PAW (picking a wedge) while reading what you wrote? Or how about BTT (bored to tears). Now that would really piss someone off! Or DFC (Don't F***ing Care!)
How about we all just start telling people how we REALLY feel or what we are REALLY doing instead of the obligatory LOL?
