Yeah, I know exactly what you mean. NOT!
Okay, this has been bothering me for some time now. IMO, I see people use it all the time but I never bothered asking them what the hell it meant. It's like "IMO dude, see ya later!" or "IMO that was some funny shit!" or "IMO, yeah IMO!" Okay I dont speak abbreviationish. And have you noticed that when people use it, its always in capital letters?! Does lol have to be in capital letters? Hell no! I was cool with lol, you know, lots of laughter? I dig that. But IMO? LMAO was pretty easy to understand, hell LMFAO was not any tougher, but IMO? I aint got a clue!
