Funny that some startups by middle class people thought "hustle," meant energetic teamwork like on a kids sports team, whereas if you had any street smarts at all, hustle means getting leverage over someone by pre-empting their ability to reason accurately, often by bullying, nagging, feigning offence, and exploiting their agreeableness by making them think they "owe," you.
Preying on human goodness like reciprocity, empathy, fairness, and agreeableness is basically what a hustler and hustle tech does.
... Something relevant to street culture rather than middle-class culture?
[EDIT] for context, my upbringing was very much not in "street culture"
[EDIT EDIT] I may be alone in this, but I dislike the HN use of the word on the grounds of both other definitions—the sports version strikes me as trying too hard to associate business with sports as a kind of borrowed glory or, in the worse cases, lame machismo, while the way it also—by my own prior association and in the ways the use of the term differs subtly from the sports meaning—brushes up against the "running a scam" definition is bad on its own, obviously, but also makes the sports association grosser, somehow.
