history: My friend is such a narcissist sometimes. He seems to think that he is the best looking, strongest guy ever and he constantly tries to brag about it to me and compare himself to me. It really irritates me when my friend acts superior to everyone in the room_comma_ since he seems to think he is the best looking and strongest guy ever when really he's not at all.
current: That's usually a sign of a lack of confidence or self esteem  in ones self I believe. 
next: That wouldn't surprise me. He has always been a bit insecure.
