When people don't care about something they often say "I could care less" but if you look at the meaning of the phrase, "I could care less" means you care. If you don't care you should say, "I couldn't care less." Think about it. If you don't care then there's no way you could care any less because you don't care at all.... i.e. COULDN'T care less. I hate when people say that. It's so lazy and wrong. Say it with me... "I couldn't care less." Rant complete.
