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”.
I always heard people use it as a synonym for pushing the envelope (like you’re walking right up to the line and prodding it with your toe), and only found out the “falling in line” meaning later. I still see tons of that usage today, and I wonder where it came from.
Britain I think?
