It doesn't even change the responses a lot. I used ChatGPT for a year for a lot of personal stuff, and tried a new account with basic prompts and it was pretty much the same. Lots of glazing.
"Head over heels" is actually a corruption of "heels over head".
It's one of those corruptions which flips the meaning (ironically, in this case!) on its head, or just becomes meaningless over time as it's reinterpreted (like "the exception that proves the rule" or "begs the question").
