What do you mean Spongebob came back to you?

It is not difficult to understand that Spongebob means to pay you back. This sentence actually comes from an expression pack. I'll lend you 20 cups of milk tea Spongebob. In fact, as we all know, Spongebob and Patrick are both animated characters, so they have no ability to borrow money at all. Many people will give this kind of Yan character to others, which means to borrow money from others in Patrick's name and ask Spongebob to pay back the money. In fact, in daily life, this sentence means asking others for pocket money, cheating on eating and drinking, and then directly not returning the money to the borrower.
