An unusual devise used to claim the foreskin of uncircumcised mens. resembles a lightsaber and runs off of the foreskin of unconseting men. used so if the rabbi sneezes during the castration the child will not loose his shlong
*bright light flashes in the sky*

Idiot 1: Guys!! a Jewish Space Laser!
Idiot 2: They just castrated all the men in the northern hemisphere!!!!

Get the Jewish Space Laser mug.
A "Jewish Space Laser" is when you receive oral sex next to a window and try to hold a magnifying glass steady enough for the beam of sunlight from the window to light all 8 candles on the menorah.
I gave my wife a jewish space laser yesterday but she couldn't light'em all.
