What exactly is a big loan shark?

A big loan shark is an individual or group that lends money at excessively high interest rates, often with violent or coercive methods used to enforce repayment. They typically operate outside the law and are not subject to the same regulations as legitimate lenders. Big loan sharks are often involved in organized crime and may use intimidation, threats, and violence to collect debts. They can be very dangerous, and it is important to avoid doing business with them if possible.
