in the same breath

[Ashiuhto]

Are the following sentences acceptable?
What does it mean by the idiom "in the same breath" ?

(1) The two things can't be mentioned in the same breath.

(2) Don't mention him and me in the same breath.

[SoothingDave]

Think of it literally. It means do not speak of them at the same time. If you say one thing and then another "in the same breath" then you are speaking of them within a very short time.

[Tdol]

For me, it also has the idea that by saying them together, you are associating them in some way (and shouldn't).

[BobK]

And, to answer the original question, yes they are. (acceptable)
