A person who acts like a Jew by coveting money, liquor, and/or drugs. There's at least one in every group of friends.
The covetous jew that is more than happy to drink a few rounds on your ass, but would never offer to buy a round for anyone and tips like a Jew.
Not neccecarily somebody who is Jewish but that one friend we all have who is reluctant to spend money under any circumstances. Be it birthdays or just everyday life they will go through extreme lengths to save a couple of bucks.
Rachel "Why doesnt karli wanna go out to dinner?"
Rhys "Duh she's a covetous jew!"
