Rolling (finance)

When you roll something in finance, it means you are extending the time you have to pay for something. Let's say you borrowed some money from a friend and agreed to pay it back in a month. If the month is almost up and you still don't have the money to pay your friend back, you can ask your friend if you can roll your loan for another month. This means your friend will give you more time to pay back the money, but you will have to pay him extra interest (money) for the extra month he is letting you borrow the money. Rolling is like asking for more time to do something but paying extra for it.
