netbragging
the act of going to a social networking website and, instead of networking, you only write about yourself, what you think, what you have said, what you have done, what you like, what you eat, what you think of politics, what you think of music ... because it's all about you in the end, isn't it.
Going to Facebook and netbragging, "There are three things that are important in my life ... me, me, and me," or "I'm sitting here thinking about me and what I'm going to do next" or "Why hasn't anyone asked about me?" or "My life is blessed ... because I say so" or "I just got a puppy!" (the last one an obvious ploy for people to ask about you)
