Basically, it's just a douchey way of saying, "I don't care." But even if you say it right, it still implies that you care somewhat... Just say, "I don't care!"
I don't like when people conclude we "wee, wee, wee, all the way home" when doing the 5 little piggies. It should be "I can't find my way home."
Of course you're not me. I do not care if you are or are not me. What about "I don't care for [noun]" instead of "I don't like [noun]"? That really upsets me.
I should stay out of this thread, 'cause things like this bug me too (way more than they should!)... but I can't help myself. Could care less, could of, irregardless... kill me now... aaaahhh. Another that drives me crazy (and only me it seems) is when people type ya'll.
Yall I remember reading a classmate's paper, she was cute, so I took an interest. When I started to see "should of" over and over on her paper, it became a total letdown.
