It's presented kinda like an
opportunity, but there's always a catch, which is usually a demand for something you're not really comfortable doing, which would usually require great effort and commitment on your part, and would really only serve to make the other person look good (and probably
momentarily at that). Oh, and you can't get the
opportunity part unless you agree to the catch, so it's basically a hustle. Usually a faux-portunity is followed by a hyped-up promise that can never be delivered. In other words, it's a complete waste of your time.
