One of mine (I have many yay neurodivergece) is when people say the phrase "a broken clock is right twice a day". The phrase is actually "a stopped clock is right twice a day." A clock that is stopped will definitely be right twice a day but a clock that is broken could be right multiple times a day or not at all depending on how it's broken. Maybe it's just a little slow running in which case it'll never be right. Maybe it's spinning wildly out of control so it'll be right a lot but still useless.
It annoys the shit outta me and it is so dumb it definitely should not. Anyway your turn.
I argued with someone on stormfront once about how "i could care less" when used sarcastically could still be some form of correct. I got mass downvoted for it.
It's generally used wrong but if said in a 2000s sitcom "I just discovered, I could care less, thank you!" laugh track way it won't translate to "I don't care" but instead "I found, I could care less than what I thought"
