Perhaps my background makes me a little more attuned to this particular word, but 'kike' practically leapt off the page to me.

In English, words ending in a single short vowel followed by a single consonant double the consonant before adding '-ed' to form the past tense. That's the grammatical rule.

I still can't tell if this project is by someone with bad grammar or some 4chan-bred bigot trying to make a double entendre, but either way, it's fucking obnoxious to see it on the front page of Hacker News.
