A jewgrinch is a noun that usually describes a selfish person who stops at nothing to get something for free, or some sort of money reward no matter how small or insignificant. Often a jewgrinch can be seen fighting over a penny found on the ground.
Gosh, Grant is such a jewgrinch. Did you see the way he just pounced on that penny that was on the ground?
