The word 'irrational' means something that doesn't make sense or is not based on reason. You can use this word when someone is doing something that doesn't have any logical explanation or seems crazy. For example, if someone is afraid of flying and refuses to get on a plane even though they know it's safe, you can say their fear is irrational. Another example would be someone who believes in conspiracy theories that have no evidence, you could say their belief is irrational. It's important to use this word carefully and not use it to insult someone just because you disagree with their opinion.
