I'm circumcised, but now when i hear the word i always think of the "Rape of Dinah from the Bible. Some heathen dude rapes a jewish girl named Dinah, and then feels bad and decides to marry her. Jews say you and your tribe have to get circumcised, and since the guy was a prince or something, he makes everybody get circumcised. While all their warriors are still in pain from circumcision, Jacob's sons go and massacre the lot of them for raping Dinah in the first place.
cool story, no?
