Yep, Kevin...I've heard "put the kibosh on" here. Not really often, but enough to get the context.

Many unusual turns of phrase like 'kibosh' and 'caboodle' are heard orally, and not always perfectly, then either repeated as what someone thought they heard ('mondegreens' come to mind), or written down and spelled as well as possible, giving us SO many variations.

There are threads in the music section about silly songs from childhood, where every couple of years some 'guest' refreshes it to post they way THEY heard it in girl scouts or grade school, ofthen with only a few words difference.

I suppose if Mudcat continues for 50 years, we'll be a major research asset!
