A cool minute
A break so big it could fit a whole football game and still have room for a nap; the kind of wait that makes your brain go numb.
You told your friend you’d meet him in a cool minute. (He showed up after a nap and a snack.)
You waited for your dad to come home in a cool minute. (He came back with a new haircut and a new problem.)
You said you’d be back in a cool minute. (You got lost on the way to the store.)
