The bro addition is mostly sexist anti-male anti-community terminology designed to boost social signaling and communicate the orthodoxy's disapproval. Also holier-than-thou social psychology. Kind of serious, kind of joking here. Also a sign of the times where people who want to make money often get funneled into these types of very bleak pyramid games.

I still quite don't get it. What are hustle bros exactly? Just people who chase short-term money?
