Could care less meaning couldn't care less. It's the same thing as how literally has come to be used with the meaning of figuratively. If you look up "could care less" in the OED you'll find it lists it under American English with the meaning "could not care less."

That’s disappointing. What next? Americans get a pass on using “it’s” when the correct thing would be “its” just because they do it all the time?
