I'm waiting,till I get blue in the face.

It's not an idiom.

The proper way to use this idiom, asal-F, is like this:

'You can wait there till you're blue in the face — I'm not coming with you!'

If you do something till you're blue in the face, you do it repeatedly without achieving the desired result until you're incredibly frustrated. (Idioms-Using English).

Please note that a better title would have been Blue in the face.

Thread titles should include all or part of the word/phrase being discussed. (Posting Guidelines)
