People who post countless arrogant and lame status updates on FB. Often self-proclaiming that they are the "luckiest people". However, said people should eliminate their excessive time posting and more time working on relationships with their straying significant other. Duh, why else do you think he bought you that nice stuff?
ie: "My friend, the egotisticalposttwitt, has just updated her status again. When will she learn that diamonds, pearls and trips all at once mean her husband is cheatin' on her sorry ass?"
