during the game tank trouble, where on 3 player two players spawn next to each other, kill each other and the 3rd person sits it out. That person is known as a jewdas because he jewed it.
An insanely useful way of detecting the presence of another Jew in the near vicinity mainly by looks or auditory sample. You are one lucky bastard if you posess this and are not in fact a Jew yourself.
Randomness #1: Hey, is that guy-?
"Guy": SHALOM!
Randomness #2: Hella yeah.
The innate ability to detect Jewishness in anotherperson. Like a sixth sense.
"Yo check out the guy with the pigtails and yammulke. Jewdar off the charts."
"Oh you mean Jedediah over there? No, he's Presbyterian, obviously, bitch."
Some guy: "Shalom baby, 'jew' lookin' mighty fine tonight."
Girl: "What!!?!? I'm not Jewish, motherfucker. I'm Hindu. Nice jewdar."
Some guy: "Oh, sorry, I didn't see that red dot on your head. And that kimono or whatever it is. Oh yeah, and I guess you do look sort of Indian too. So, how 'bout you take me back to the reservation with you? You can be Pocahontas and I'll be the John Smith. Then we can bang."
