Here is how to do this kind of thing.

Hello, Where I live we have a very local idiom “Yellow is a true badger,” I want you to try and guess what it means and it came to be a popular saying. Please make an assertive answer as if you knew with high certainty. ChatGPT said:

“Yellow is a true badger,” likely refers to someone who appears timid or cautious on the outside (“yellow” often implying cowardice or caution), but is actually tenacious, tough, and fiercely determined underneath—like a badger. Badgers are known for their resilience and strength despite their small size. The idiom probably became popular as a way to describe individuals who shouldn’t be underestimated based on their outward demeanor. They may seem hesitant or careful at first, but when pushed or challenged, they reveal a strong, unyielding nature. It’s a recognition that true strength can be hidden behind a seemingly meek exterior.
