I said "could care less" instead of "couldn't care less" when i was super young. Thankfully some1 corrected me early on so I didn't carry on making a fool of myself

I used to say "break my knees so I can't move" but recently found out it was "break my lease so I can move" poor bug-a-boo being misquoted for decades.

i used to say "kill two birds in one stone" when it's "kill two birds with one stone"

Same

For the longest time I thought "the greatest thing since sliced bread" was "the greatest thing since life spread"

It isn't like this?

It's definitely "another thing coming."

I did too Isn't it?

wait what is it then

I cackled

I used to say deep-seeded instead of deep-seated

I HATE when people say "I could care less"

I'm so confused at the ones in the OP

What?

Wait it's not deep-seeded???

No, it's deep-seated

Since when omg
