I could care less about grammar
I admit it, I can be one of those word snobs at times. I wince at the countless misuses of there, their and they're. I cringe when people say irregardless (non-ironically, of course). And for some reason, today I've been bombarded with the phrase "I could care less" about such and such.
That makes no sense! Why would you say "I could care less" to communicate your lack of care about something? What's more, it means the opposite of what you're saying! If you don't care at all (as in, zero), then it's impossible to care less (negative caring?) So no, you could not care less!
Well, I thought getting that off my chest would make me feel better, but it doesn't. I should care less.
