The idiom "fall for something" means to be tricked or deceived by something or someone. It is often used when someone believes something that is not true, or when someone is convinced to do something that they later regret.
For example, if someone is told that they have won a prize but they have to pay a fee to claim it, and they believe it and pay the fee, they have "fallen for" the scam.
Another example could be if someone is convinced to buy a product that they don't really need or want, and they later regret the purchase, they have "fallen for" the sales pitch.
