Why do people mistakenly say this when the expression is "I couldn't care less?" I COULD care less suggests that you do in fact care, but I know most people mean I COULDN'T care less (as in they don't care at all), as what they go on to say supports the latter, and if they in fact meant the former they would be contradicting themselves. Why do people find this expression so difficult? Why do I care so much? I don't know the answer to either question, but people please, the correct expression is

I COULDN'T CARE LESS

which is something I COULD (and probably should) care less about.

Step forward the wonderful replies stating that you couldn't care less about this forum =] Life's good.

^^lol that

It's just one of those phrases that people use without even thinking about it. It always gets me when people say or write;
Could of, should of, would of, will of.
The phrase is could have! Of is not a contraction of have.

Edit: Piplup c-c-c-combo breaker.

... I could not care less about this!

That graph highlights the phrase perfectly, although it is trying to be witty and smart. The whole point of I couldn't care less is that it really is impossible to care less as you don't care at all.

And yes, I agree, could of, would of, should of = Big no no. Was in a test I did at work recently - amazing how many people don't realise it's could have, would have, should have.

I couldn't care less because it's impossible for me to not care about you.

I certainly could care less about that and other grammatical errors, but I don't think I will.
