I want to thank Chief Clancey Wiggum for helping me win a gentleman's bet. I have seen the word 'kibosh" in print many times, but only heard it pronounced once: by Chief Wiggum on the Simpsons. He said something along the lines of "We put the kibosh on your tele-marketing scam."
My friend said it was prounced: keh-bosh.
I insisted it was: kai-bosh.
Who was right? See the answer here.
