An individual (usually a friend) who takes advantage of your purchases to gain points for their rewards card of the corresponding place of sale, reaping the benefits of someone else's spending.
a) Yo, he's such a points jew, always sneaking his rewards card in when I pay for shit.
b) Stop being such a points jew man, it's goddamn annoying.
A jewpoint is reached when a Jew runs out of money and becomes exceedingly greedier, angry, sweaty and rude - that is a jewpoint. Caution must be taken when you're around a Jew who reached their jewpoint.
My God did you seeEsther that day? She was full on angry, rude and bitch. What was up?
She reached her jewpoint. Probably was out of money and was pissed about it. That's what happens when you reach your jewpoint.
