When you get that god awful rumble in your stomach and a cold sweat forms hinting the idea that a gastrointestinal catastrophe of epic proportions is upon you, you grab your mobile cellular device and quickly sit down as the turd tea evacuates from your ass. Feeling the relief that you made it without having shit running down your leg you decide to open up face book on said cellular device and start posting to peoples pages....whether you tell them the exhilaration of what just transpired or just a simple, "hey what’s going on for tonight?" You have just engaged in "poop posting"
Steve (to mikes facebook page): Yo bro, you need to see this massive mud pile, I shouldn't have had all that bud light and hot wings
Mike: Where the hell are you?
Steve: On the shitter!
Mike: Dude you were just poop posting my fucking page...nice!
