"Pay up" is a colloquial expression that means to pay someone or to settle a debt that you owe. It is often used in a forceful or demanding way, especially when someone has been waiting for a long time to be paid. For example, if you owed your friend money for lunch and they kept reminding you to pay them back, they might say "Come on, pay up already!" You can use this expression in situations where someone owes you money and you want them to pay you back.
