What makes a guy a loser?

There’s a guy I know who is physically attractive, professionally sound, intellectually brilliant, but psycho-socially there’s a glitch.

Someone from our group mentioned the guy is an absolute loser and I shouldn’t associate with him. So I asked what makes him a loser and was told to just look at him… see who he hangs out with… and that was it.

He does tend to pick off bottom rung guys to be his friends. But he insists on remaining connected to me.

There more to the story obvi, but what I’d like to know is what makes you look at a guy who seems successful and so on and think he’s a loser?
