"Fool around" is an informal expression that means to engage in light-hearted, playful behavior, often with no clear purpose or goal. For example, you can say, "I spent the day fooling around with my friends at the park," or "Instead of studying, I just fooled around on my phone for hours." It's important to note that "fool around" can also be used as slang to describe engaging in sexual activity, so make sure you're using it appropriately in context.
