Okay kiddo, have you ever heard of someone who lends money to people who need it, but then makes them pay back way more than they borrowed? That person is called a loan shark.
Loan sharks are not like regular banks where you borrow money and pay them back with interest. Loan sharks charge really high interest rates that can be impossible to pay back. They often target people who are desperate for money and can't get loans from banks because they have poor credit or no collateral.
When someone borrows money from a loan shark, they may have to give the loan shark something valuable like their car or jewelry as collateral. If they can't pay back the loan, the loan shark can take those things as payment instead.
Unfortunately, loan sharks are usually very mean and scary. They can threaten people with violence or harm their families if they don't pay back the money. That's why it's really important to avoid borrowing money from a loan shark and to only borrow from reputable lenders who don't charge unfair interest rates.
