Cough Up
give unwillingly
不情愿地给予
Say, Greg. Did you finally get that computer that you wanted so much?
Not yet. I needed to raise a couple of hundred dollars more.
Is it going to take you a while to raise the money?
It would have taken me forever, but dad said he'd cough up the money I need since I'm going to be using the computer for my school work.
Maybe it was difficult for your dad to give you the money - but then, he knows that it's for a good cause.
Think about what you should do, not about what you should have done.
