come up for air
1. Lit. to lift one's head out of the water to breathe. After staying under water for almost a minute, Jason had to come up for air.
2. Fig. to stop what one is doing for a different activity or rest. Whenever you get off the phone and come up for air, I have a question for you. I want you to go to the store for me when you come up for air.
3. Fig. to stop kissing for a moment and breathe. Don't those kids ever come up for air? When are you two going to come up for air?
