The idiom "mad as a hatter" means that someone is behaving in a crazy or irrational way. This phrase comes from the fact that hat makers in the past used to use a chemical called mercury to make their hats. Over time, the mercury would affect their brains and cause them to act strangely.
Today, we use this phrase to describe someone who is acting in a similar way, even though they may not have been exposed to mercury. It's important to note that this phrase is not meant to be used to insult or stigmatize people with mental health issues.
You might use this phrase when someone is behaving in a way that is unexpected or irrational. For example, if your friend suddenly starts talking to themselves and acting strangely, you might say "Are you okay? You're acting mad as a hatter." It's important to use this phrase with care and sensitivity, as it can be offensive to some people.
