Maggie Acker uttered this beauty when talking about her car that stopped running. It is a congruent conflation of “kicked the bucket” and “shit the bed”, both idioms referring to something or someone that died or failed. “Shit the bed” is a relatively new idiom (I found it in the Wiktionary – https://en.wiktionary.org/wiki/shit_the_bed ). It usually refers to something that breaks and can’t be repaired, like a cell phone. Interestingly, in the U.K, it means to express surprise. The mental mix up probably also was caused by the similar sounding words “kick” and “shit”. A big, big thanks to John Fischer who heard this one and passed it on.
