Please state in which country your phrase tends to be used, what the phrase is, and what it should be.
Example:
In America, recently came across “back-petal”, instead of back-pedal. Also, still hearing “for all intensive purposes” instead of “for all intents and purposes”.
This one never gets me anywhere, but “begging the question” is actually a logical fallacy where you assume the result and use that as the basis of your argument. Otherwise, it raises the question.
The same goes for the exception that proves the rule. People use it as a magic spell that does away with unwanted evidence but it’s self explanatory. No parking on Fridays means you can park every other day.
There’s an exception to every rule (except that one)
That’s actually a post-hoc rationalization; in the original phrase, “proves” has a meaning closer to “tests”. But, yes, people use this one all the time to justify being wrong either way.

Probably not according to Wikipedia.
and how is that post-hoc?
If I claimed I didn’t get a ticket that day because I wore my lucky socks that would be post-hoc. I don’t see how that applies here.
How do you feel about other words or phrases that have different meanings in specific fields vs common use? Like a scientific theory is very different from your buddy’s theory about what the movie you watched meant. Since beg is a stronger word than raise, some statements scream out for questions in response, while others merely give rise to some further need for clarification.
