That's Cool

That's Cool is a phrase people tend to use when they don't know what to say or are uninterested.

In this context, the word "cool" isn't necessarily positive, and becomes more neutral. This is why there is sometimes confusion when the phrase is used.

Person A: Hey man, did you hear I just got a new car?
Person B: That's cool.

OR

Person A: Did you know Nick broke his wrist?
Person B: That's cool.
