Poser
A guy who talks like he's known you his whole life even though he's never met you is a strange kind of poser.
The boy wasn't getting the attention of the kinds of guys (besides knowing what his band's name was) he wanted attention from, so he wrote lyrics about fighting with people he never met before, so that he's got their attention if he really wants it. His target didn't give him much thought before, but now thinks he's a poser.
