Couldn't Care Less Edit Meaning

1.

The proper way to express how you don't give a crap about something - you really don't care about something and it's impossible to not care any more. The common but incorrect variant "could care less" (which would technically imply that you do care about something) is widely used because of either a translation mistake into English, or those who blindly use phrases without taking a moment to understand their actual meaning.

Person A: A company just got sued for patent infringement!

Person B: *yawn* Oh really? I couldn't care less.

See apathy, could care less, care, don't care, generic
