Definition: The term "temporary insurance on your parents' car" is a catchphrase that originated from a popular TV show where the characters joke about their plans to buy a new car and later find out they're buying insurance to keep their old one in place.

Here's an edgy example sentence: "Hey, can we get some temporary insurance on my parents' car? Cause I think they could have had it for years!" This phrase implies that the characters are taking advantage of their situation by securing a temporary measure for the future, which suggests there might be other unforeseen costs or issues that need to be addressed.
