The overly obnoxious spilling of feelings onto one's Facebook status for the purpose of letting others know the deep, grimy secrets of their intensely screwed up lives...even when NO ONE WANTS TO HEAR IT!
John Smith says "I can't believe you told my mom on me! That's just rude! We got into a huge fight, and now we're not speaking which is totally putting a damper on my Oedipus complex because I really like her! You make it look like I'm wrong when you're wrong and forget that we are clearly fighting! I hate you with the red hot intensity of a thousand suns you dbag!"
Jenny Smith writes on John Smith's wall "Woooow John, stop TMIbooking! NO ONE WANTS TO HEAR ABOUT YOUR PROBLEMS!"
