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 say “I could care less” and then follow it up with, “but I’d be dead”. Correcting “I could care less” is dumb because you literally can care less about lots of stuff, but saying the phrase indicates you just don’t really care.
