When the Chuck Berry song My Ding-a-Ling was banned on British radio as being too rude, Punch published a cartoon of record executives sitting around a table, and one is saying “Can’t we find a euphemism for ‘Ding-a-Ling’?”
Well, it was very well known by that time, since the word shows up a lot in Victorian-era porn.
I’m reminded of something a friend once told me:
“You ever been whipped by a pussy? It’s not so bad.”
