To refill is to fill something again, the way you refill your motorcycle's gas tank or refill your cat's water bowl when you notice it's almost empty.

You can also refill a prescription, by going to the pharmacy and getting another month's worth of medication. The bottle of pills itself can also be called a refill. People commonly use this word as a noun for the act of filling up, too: "Hey, grab that waiter and ask for a refill on the Cokes!"
