- keyster
- To vaudevillians this word meant suitcase, but the meaning changed to mean one's posterior.I can see why and how it changed, but have never been able to confirm it. [Didn't the vaudevillians spell it keester or keister?]My friend was 90yrs. old and corrected me on its use and meaning.
He fell on his keyster. He sat on his keyster.
