Fork Over(hand over, give)
Hey, Dan. How come you're looking so sad?
It's nothing , really. I unexpectedly bumped into Ralph and he asked me to fork over the ten bucks I owed him.
Did he expect you to pay him back right then and there?
Yes, he did. It was all the money I had, and I had to hand it over to him.
Don't complain. After all, he did you a favor by lending it to you in the first place.
