The expression "piss about" means to waste time or do something unimportant or silly instead of doing what you should be doing. It's a British slang term that can be used in informal settings, like with friends or family, but may not be appropriate in more formal situations. For example, if your teacher asks you to do your homework and you spend the next hour messing around on your phone instead, your teacher might say that you're "pissing about." It's important to remember that this is a casual expression and may not be suitable in all situations.
