| The other thing that people often overlook, is that "could care less" and "couldn't care less" mean exactly the same thing IF the person saying "could care less" was intending to be sarcastic. As in: "I couldn't care less about this test." (literal) "I could care less about this test." (sarcastic) Yes, the actual expression is "couldn't care less" but I can easily see how people think it is "could care less" (in a sarcastic tone). Same as "by the waist side" instead of "by the wayside." The term "wayside" is so rarely used now that people mishear it and rationalise the alternative definition that does make sense. There are other examples too (correct on the right): - Nip it in the butt vs. Nip it in the bud - One in the same vs. One and the same - You’ve got another thing coming vs. You’ve got another think coming - Each one worse than the next vs. Each one worse than the last - On accident vs. By accident - For all intensive purposes vs. For all intents and purposes - Extract revenge vs. Exact revenge - etc |
