That’s a bit of a word salad, but I assume it’s just saying that it’s a coincidental euphemism. Like if a non-English speaker said “Did you know? The English term melon baller literally translates to breast testicler”. It’s not like it’s a high bar.

So just like the use of the word “nuts” to refer to testicles.
