couldn't care less
Maximally not invested
Couldn't care less means to have zero interest or concern about something: I couldn't care less what he thinks of me.
The phrase emphasizes complete indifference—caring is already at its minimum, so it can't go lower.
The illogical variant could care less has become equally common in American speech, despite meaning the opposite of what speakers intend.
