Idiom of the day :- Cough Up

Usage, examples and definition of the Idiom :-

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.
