0167 I couldn't care less - English Idioms

Explanation

An expression indicating complete indifference or lack of interest in something.

Origin

This phrase emphasizes the lowest possible level of caring (zero).
The logic is that the speaker's level of caring is so low, it could not be any lower (less).
It's a straightforward idiom emphasizing apathy.
A common, grammatically debated variant is I could care less, which illogically implies some level of care exists, but it's used colloquially with the same meaning of indifference, often sarcastically.

Alternatives

Slang/Informal:

I don't give a damn.
I don't give a hoot. (Milder, somewhat dated)
Not fussed. (UK/Aus meaning not bothered)
Meh. (An expression of indifference or apathy, often online)
As if I care. (Sarcastic)

Vulgar/Emphatic:

I don't give a fuck. (Very strong indifference)
I don't give a shit. (Strong indifference)
I couldn't give a flying fuck/shit. (Even stronger emphasis)
Kiss my ass. (Implying the topic/person is beneath consideration)

Milder:

It's not important to me.
That doesn't really concern me.

Situational Appropriateness

Informal to semi-formal.
Can sound rude, dismissive, or confrontational depending on the context and tone. Avoid using it about topics genuinely important to the listener, unless you intend to be dismissive.
Generally inappropriate in highly formal or professional settings where diplomacy is required.

Misunderstanding Warnings

The main issue is the common but illogical variant I could care less, predominantly used in the US. Non-native speakers might logically assume it means the speaker *does* care somewhat. Explain that colloquially, it carries the same meaning as I couldn't care less (zero care).
Can be easily perceived as rude if the listener doesn't expect such blunt indifference.

Examples

He thinks I'm upset about his comments? Honestly, I couldn't care less.
Whether they come to the party or not, I couldn't care less.
She tried to make me jealous, but I couldn't care less about who she's dating.

Dialogue

Person A: Did you hear that critics hated the movie? They gave it terrible reviews.

Response Patterns

Can also be delivered with a shrug.
