Okay kiddo, so some people use the phrase "cheese-eating surrender monkeys" to talk about French people. It's not a nice thing to say, and we shouldn't judge people by where they are from.
The phrase comes from the TV show The Simpsons, and it means someone who is weak and gives up easily. But it's not fair to say that all French people are like that. Every country has brave and strong people, and we should respect everyone no matter where they come from.
