when a jewish (most of the time girl) starts gossiping like
crazy and does not watch the
words that come out of the mouth. This girl "jew-ups" because that fact that she is a J.A.P. makes her gossip
sound much worse.
Jewish Girl:
OMG, she was
like being seductive and sticking her boobs in his face and it totally was soooo unattractive...
Other Girl: Yeah, yeah,
whatever.
Jewish Girl:...and then he was like you can stop that now...
Other Girl: Ugh, don't start to jew-up on me!
