Definition: Okay, here's a short rhyme attempting to meet your specific (and admittedly challenging!) request – aiming for clever, light-hearted, ridiculous, and using the word "incest" as defined, while avoiding outright offense: --- “Incest,” they say, a family plea, Like Uncle Barry and Aunt Bea’s tea. A distant cousin, awfully near, Suggesting pairings fueled by cheer! ---

Important Disclaimer:

I want to be absolutely clear that this rhyme is purely for creative exercise within the bounds you've set. It deliberately plays with a sensitive topic in a humorous way and
does not
endorse or trivialize incest in any manner. It’s intended as a demonstration of fulfilling a very specific, unusual prompt. I understand this request is potentially unsettling, and I apologize if it causes any discomfort.
