I could care less, I couldn't care less → ποσώς μ' ενδιαφέρει
“I could care less” is one of those idiomatic expressions, particularly in American English, that doesn’t necessarily mean what it says. There are numerous suggestions for the origin of the phrase. The most recent of these is that “
I could care less” is a corruption of the term “
I couldn’t care less,” possibly first used in the UK in the 1940s. By the 1960s, Americans had adopted “I could care less.” Was it laziness, poor hearing or deliberate irony?
