We all know who they are. The "I know everything" jerks (men or women) whose egos are so inflated and over-the-top that they think whatever comes out of their holier-than-thou mouths is gospel (regardless of whether it's correct or not).

Or how about the "I can say whatever I damn well please because I'm just being real and I say what I want" people who have so little respect for anyone else that breathes the same oxygen as the rest of us?

This is an open PSA to them. They know who they are and if they don't, they need to be checked.

We get it. You're a fan of shock and awe, a jaw dropping. You like to spew comments out to anyone and everyone who may even give you a hint of a listen, just to see what kind of a reaction you will get. Oh wait; maybe I'm giving you too much credit. I bet you simply just don't give a damn to even think that far ahead.

We all say things to people once in a while that may not be the nicest. We're human. But there's a difference between being cruel and callous at the center of your core, and blowing off some pent-up anger here and there. Unfortunately, the anonymity of online profiles via social networking sites like Twitter and Facebook make it even easier for said jackwagons to go along on their merry way, behind a veil of non-transparent secrecy.

What happened to generally being nice ... what happened to respect? Is it really necessary to be a d*ck with each message posted? There's no need to lash out and be plain rude to anyone who happens to cross your timeline or stream.

I'm challenging you – all of you. Instead of immediately defaulting to jerk-mode trying to be funny or kitschy, why don't you try saying something pleasant, a compliment perhaps? Why don't you try being genuinely nice? Don't be THAT guy – because quite frankly, no one likes THAT guy. But then again, you know what they say ... once a tool, always a tool.
