The friend who only ever wants to talk about herself. You tell her you’re going to Mexico for vacation, then all of a sudden you have to listen to her talk about how she went to Mexico with her Aunt Becky and blah, blah, blah, me, me, ME. This girl may not even be as self-absorbed as she seems. Her real problem is that she has a listening deficiency and only pays attention to parts of conversations that she can make about herself instead of paying attention to what you have to say. Real friends are capable of listening to you.
